Hi Phil,
The solution I am at now is to have multiple things working in tandem, but I was hoping to condense and see if there exists a simpler solution. Here is what I have:
A note that has a calculation using the pulldata function from a .csv which has a relevant ${sitelocation} linking it to a previous question. This then populates my desired known locations with the predetermined UTM's.
The next thing is a geopoint appearance of hide-input and the default with the office location and the relevant set to selected(${sitelocation}, 'other'}). Also a pulldata calculation so my end result is in UTM's.
So, essentially I added the hide-input appearance disabling the visual map with location dots on the website for the output data. I was hoping to maintain this, but I don't see how to do all the things I need and also keep the map. It will only output the default office location if I remove the hide-input appearance. So I might as well remove it.
What I have is functional enough, but please share if you know a way to better what I have.
