Custom order of Relationship Selection options

[ChristineTombleson1]

I have related feature classes and tables in my Field Maps App.  After selecting a feature on the map, you can click the relationship link in the bottom left hand corner and a list of relationship layers or tables will appear (as in picture below). I would like to put this list in a custom order to guide a user to select certain relationships first over others. How can I determine the order of this relationship class list?  Thank you!

Following as I would also like this list to be configurable.

In addition to having related layers/tables configurable I would also like to see the records themselves sortable. (works on same layers but option is missing on tables)
