possibility to make "empty" non selectible in part selection?

is it possible to remove "empty" from a certain part selection list?

secondly i was also wondering if its possible to order the lists of parts in the part selection?

 

I think that you have ro add {optional=false} somewhere, not sure where though.

 

That's for beams. Not slots.

 

Oh, must've read something wrong then.

 

Hmm what a same :/ would really love that option xD
