For Each UI Element needs an input variable property

Consider a web page with a list of users. For each user there is a list of groups in a pulldown. We need to loop through the users and then for each user loop through the items in the pulldown.

So we’d use a For Each UI Element on the users, but there’s no way to then put another For Each UI Element inside it and put the parent FEUE’s CurrentElement into an input for the child FEUE.
