Template grid: single selection and maintain ánd trigger a microflow at single click

Hi,

Has anyone found out how to trigger a microflow with a single click in a template grid when it is set to "single selection and maintain"?

At single click: It needs to trigger a microflow that sets an association (non committing) between two entities. I need a multiple of these template grids on one page and want to commit the associations when triggering a button outside of all these template grids.

Single selection and maintain: It needs to show to the user that it selects the right item on the template grid. This is not solvable with a dummy attribute (boolean), because the entity can be used by severable people at the same time, causing confusion.

I hope to be hearing some good ideas!
