TL;DR
Middle click to add building to deconstruction/upgrade plannerWhat?
Add the functionality to press middle click / some other button combo to add a filter into either plannerWhy?
Currently the only way to add a filter to deconstruction/upgrade planners is to put them in your inventory and add each building you want to affect one at a time, it would be really convenient if you could simply use a click to add a buildingYou usually dont want to upgrade every machine in some area or deconstruct an entire factory block, and whatever you want to deconstruct / upgrade will most likely already be in world
