I am trying to make a settings page for an application that uses a map. In the settings I want the user to be able to select the "type" of map they want to show up on default. That way they don't have to switch to their preferred type every time the map loads. 

I was going to just call it in an aggregate and let them assign it to a value that I save. But when I attempt to use Type as the source for an aggregate I get the error, 'Type' is defined in an integration or in a Library and cannot be used as an Aggregate Source. 

Is there anyway for me to save my users preferences for the map type? I'm aware that you can manually select it when the map loads, but I want to avoid them having to go and clicking that every time.

Thanks!
