Currently a station group needs a provider and n requester station. I understand the use case, to group eg the red chips provider station with all requester stations of the ingredients deliverd to the red chips factory. But in some cases I may not have a provider station, were the finished product goes in and instead it's belted to the next factory nearby. So it would be nice, if I could a station group exclusively with requester stations only. This would also include to be able to customize the group name.

I build a fake provider station for that special case and use it as a shuttle parking station.
And you could name that base as you like ( in the constrains of the configured "provider" strings)
