TL;DR
Allow Players to change the Anchor Points of Blueprints to place them better.What ?
Right now, the anchor point of the Blueprints is in the Center of the Blueprint.For small BP it´s good, but as soon as you get blueprints, which are bigger than your screen, it gets really hard to place them correctly.
Make a hotkey so we can change the anchor point to different places.
The 0 on the Picture is the anchor point right now.
For the most bigger BP the 4 corners should be good anchor points (Number 1 - 4).
In some cases it might be even better if you could have anchor points between these numbers (for example between 1 and 4)
