As of release 5 you can now desigate the licensing that a station consumes.
Any set that is designated as Trusted will not consume a license but can be used for phantom purposes. I havent found a gotcha yet.
With Key assignments, nod to M1Tel, they have been the only way until recently but historically have been hard to understand for the common user and have on occasion been dificult to change or delete. (or worse, accidently deleted along with the host set)
