Am I understanding correctly that you can’t put a link to a blueprint from the library into the BAD Chest?
I can only put a copy from the inventory. (I make a copy so I don’t lose the blueprint in the library.) Or am I doing something wrong?

I don’t really like the fact that changes I make in the blueprint library are not reflected in the blueprint that’s stored in the chest.

Now (in version 1.4.14) you can either use the blueprints directly from the map's library or copy it to the BAD chest inventory.

Have fun :)
