Can a template grid be used in a pop-up form of a reference selector

1
In our booking system customer can select a variety of (sub)products in one booking. In the select form we want to show images of the products. The use of a form with templategrid generates errors. Any other solutions????? Looks like something that should be possible !!

You can use a microflow button on the reference set grid instead of the add button and open a form with a template grid and again a microflow button to 'select'. The last microflow should refresh as well.

A trick might be to build a form with the enclosing entity of the main form also around the products form to know the reference.
