[Ideas] Ability to bump all downstream nodes in a flowchart

I like the way that when you insert an element in a flowchart and there isn't quite enough room, that it "bumps" everything down to make room for it.

I would like a way to do that myself, on purpose - to grab or click on a node and use a modifier key (Shift? Alt?) to move everything "downstream" of that node like the automatic insertion seems to.

This would be very handy with Switches in particular :)
