You can define a fill in GDL but you can't define a pen for a pen set.
You can set the pen number to be used - but that is all.
However I could see the need to be able to set the RGB colour and thickness of a user definable pen (that is not part of a pen set) so that could be used in an object.
Then regardless of the pen set chosen that pen colour would never change in the object (unless altered in the parameter settings).
Zones already have an RGB pen colour that is not part of the pen sets.
If you save a zone as an object you will get an strange pen number (i.e. 1008) and it will just appear white (with an error message to say pen exceeds range) rather than the original zone colour (at least it does for me).
But there is no way to define this pen colour - which would be nice.
