Instead of assigning to an address, could you select a feature from the WebMap that you could assign a task to? For example, we are in the agriculture space and would love to send a task that the scout needs to go look at a particular field boundary.
HI Jessica, thanks for your question on Workforce.
In the Workforce web app, you can click on existing features/assets in the web map to start creating an assignment. When you start from an existing asset / feature, we use the pop-up title for the feature as the Location instead of the address. So, in your example, you can configure the pop-up title of the field boundary to be whatever name or title you'd like to use as the Location.
Give this a try and let me know if you have any questions on this.
Craig
