You can place custom markers on the BaseManager maps to represent non-Baseline items. For example, you could create a custom marker to show the location of a pump station.
1. In the main BaseManager interface, click the "Maps" tab, and then click the level that you want to add a custom marker to. A blue check mark displays next to the map level that is selected.
Note
If you want to add a custom marker to a specific controller, make sure that controller is displayed in the BaseManager footer. To select a different controller, click the "Menu" icon 
in the upper-left corner of the BaseManager page, and then click "Sites and Controllers". Continue drilling down until you can select the desired controller.
2. Save a new map view, if necessary. Refer to How Do I Save a Map View?
3. Click the "Edit" button in the lower-right corner. The Edit Maps menu displays on the left side of the page.
4. Click the "Markers" option, and then click the Custom Markers option.
Note
To search for a custom marker, type a letter, number, or word in the Search field that displays at the top of the Custom Markers list. The list will refresh and show the custom markers that match your search term. Do not press the Enter key after typing in the Search field.
5. Click "Create a Custom Marker". The Custom Marker dialog box displays.
6. In the "Label" field, type up to 2 characters that will identify the marker on the map.
Note
If you leave the Label field blank, an error will occur when you save the custom marker. The custom marker will not display on the map.
7. Click one of the color boxes to apply a color to the custom marker.
8. In the "Name" field, type up to 25 characters as the name of the custom marker.
9. In the "URL" field, type or paste a URL to a web page related to the custom marker.
10. In the "Description" field, type up to 70 characters as a description of the custom marker.
11. In the "Notes" field, type or paste any notes related to the custom marker.
12. Click "Save". The Custom Marker dialog box closes, and the name of your custom marker displays in the list on the left.
13. Make sure that the intended location for the custom maker is visible on the map. If it isn't, click and drag the map so you can see the location.
14. Find the name of your custom marker in the list on the left. Click the "+" next to the custom marker's name. The cursor changes to cross hairs.
15. Move the cross hairs to the location on the map where you want the custom marker to display, and then click the left mouse button. The custom marker displays in the selected location.
16. To move the custom marker after you have placed it, position the cursor on custom marker on the map. Click and hold the left mouse button, and then drag the custom marker to a new location. Release the mouse button.
