I don't know how it's endorsed on UK licences but my Swiss licence simply has a "PBN" endorsement which is applicable to any and all type-specific IR ratings. It's entered separately from the type ratings on my licence, so doesn't need to be repeated for each new type added.
My opinion: I believe the idea behind the endorsement is to simply check for the knowledge of the PBN procedures and the differences compared to conventional instrument flight procedures, rather than checking how PBN is flown on each type of aircraft in its associated systems. In other words, I think they just want you show that you know how to program and fly an RNAV approach and the nuances that come with it (TAAs, fly-by vs fly-over waypoints, LOS requirements, use of AFCS during PBN operations etc). Once you've gotten the PBN endorsement you shouldn't need to re-do that course for each type you fly (although future proficiency checks require you to conduct at least one PBN approach IIRC).
