Feature request - auto decon entities

[SophieFitz]

In my current Seablock planning save, I upgrade buildings/builds to different processes between stages. I want to be able to add/remove entities that interact/overlap with future stages. Could this happen with a toggleable option?

The toggleable option being: Auto-deconstruct the overlapping entity - the one(s) on any lower stage - in the nearest (above) stage that has the overlapping entity. Does this make sense?

So I have a building on a later stage, and I want to place an inserter on a lower stage into the same space. As of a recent update, this is no longer possible (yay for bugfix, nay for my workaround no longer works :( ). So my solution to this would be that the inserter I'm placing would be auto-decon'd on the stage with the building that is blocking it.
