If you want to add a new PIN icon which is not present in the system-supplied list of PIN icons, then you can create a new PIN icon (for an unlisted equipment).
Click the PIN creation annotation icon and then click on the portion of the floor plan where you want to place the PIN.
The Select pin icon pop-up will appear now on top of the Viewer screen (Viewer screen will come in the background) immediately after the PIN is placed.
Screenshot below displays the Select pin icon screen:

To create a custom pin icon, click Create New Icon located in the bottom-right corner of the screen.
Once you click on the Create new icon button, you will get navigated to the Create new icon screen.
Screenshot below displays the Create new icon screen:
Enter a name for the pin icon in the Icon Name field and select the desired color. A default color is provided and can be used if no change is required.
Select one or more categories for the pin icon by selecting Shut-offs, Equipment, Emergency, and/or Other. The Shut-offs category is selected by default.

Now click on [Save] button to successfully create the new pin icon.
Now, you can go ahead and create a new PIN based on the newly created PIN icon.
