Geometry Picker Maximum Geometries

Hi,

I have a geometry picker with a geometry type of point. Behind the scenes this will save points into a multipoint feature service layer. I have set the maximum geometries to 3 by default, however I want to be able to change this setting on the change event of another form item (same form). Just before the geometry picker, I have a number slider allowing the user to request from 1-3 trees. Based on how many they change this to, I want to change the maximum geometries size. I can't see a property you can access to change this. Is it possible to change it via workflow? If so how?

I also would like to change the text that shows for each location added. By default the text says 'Proposed Location' as that is what I set it to, but I want to dynamically change it to be 'Proposed Location 1', 'Proposed Location 2' etc for each point added.

Thank you!
