Setting up custom class for a cell

I’ve been using Page Builder for a while now and by me there’s really something missing…

Let’s say you create 3 cells row.

Cell #1 has 1 widget,
cell #2 has 3 widgets,
cell #3 has 2 widgets

My cell #2 holds 3 image widgets that are supposed to be shown with no bottom margin.
Other cells hold text and bottom margin is just fine.

The point is I can’t target cell #2 unless I’m able to assign custom class to it. But I can’t
since there’s no such a feature.

It would be really nice for users to be able to edit specific cell.
