Allow editing of blueprint icons within the library

[Recon777]

TL;DR

Please let us edit the blueprint icons from within the blueprint library similar to how we can for blueprints physically in our inventory.

What ?

Currently, in the blueprint library, we cannot change the icons which visually represent the blueprint. See image below:



However, we CAN edit the icons if the blueprint physically exists in our inventory, as opposed to being in the library. See image below:
Additionally, the checkboxes for Tiles, Entities, and Station Names are available in this UI but not the previous one.
There is also an "Export to string" button which would be nice to have for library blueprints



I suggest the UI which currently edits the physical blueprints in our inventory be made available for library blueprints.

Why ?

The reason for this is because often blueprints need their icons changed even if they have already been placed in the library. Currently, the only way to change icons of library blueprints is to copy them into the inventory, edit the icons, and then copy them back to the library. Then, delete the old one. This cumbersome process could be made easy by allowing editing of library blueprint icons.
