TL;DR
Adding modules to building should not wait for building to be constructed.
What?
When building with modules is scheduled for construction by blueprint or copy&paste, construction bots with modules should be dispatched immediately and not wait for building has been constructed.
Why?
To construct buildings with modules faster.

No. This would cause bots to have to wait until building is placed and if there are no items that place building that robot with modules would be stuck or more complexity would be needed with robots task scheduling.

Bots already wait to construct building in place sopmething that needs to be deconstructed.

Robots won't be assigned to build something until a robot is assigned to remove anything that needs to be deconstructed.

Doesn't landfill behave this way? I believe I've seen bots waiting for landfill to be places before placing the building.

IIRC, why is it OK in one case and not the other?

Could we change the suggestion to similar behavior? So the module bots will dispatch when the building's bot does?
