TL;DR

Paste a blueprint of higher quality over existing lower quality

What?

I want to copy paste a blueprint with higher quality (e.g. an array with rare accumulators) over an existing installation with the same items with lower quality without having to force-paste, so anything that does not match the blueprint is left alone

Why?

If I pick a single quality item and hover over an existing building of same class but different type, it shows green and I can just drop it.
If I Copy the same building (or more) and hover, it shows red even if it is just a quality upgrade. In this case, I have to force-paste, which might destroy other buildings.
Pasting should work the same way as plain building

Is there a compelling reason you don't use the upgrade planner instead of a blueprint ?

Good point, mainly because I did not know the configurable upgrade planner...
