It would be cool to directly place ghosts for robots from the construction GUI
For example:
left mouse - hand build 1
right mouse - hand build 5
shift-left mouse - place ghost
Reason and long description:
With the instroduction of the personal Roboport my personal robots steal the items from my inventory
and I can't place ghosts anymore even though I have enough items in logistic system.
Thats why you can't ghost draw a 100 line belt when you only have 1 belt in inventory.
And you are not forced to keep every item in inventory just to order your lazy logistic droids to get working.
I know we have blueprints and soon blueprint book for that but I like ghosts

It's only a small addition to the controls but I think it will add alot of convenience to the automated building system and result in faster building, maybe this is already doably by modding ?
