"Member Of" Solo Acts as Backing Artists

In adding artist details, I've found an EquipBoard issue with "Member Of" listings that I'm hoping can be easily resolved.

It is currently not possible to associate an artist as a "Member Of" a solo act. Example: Robbie Blunt, guitarist for Robert Plant when he launched his solo career post Led Zeppelin.

I've been scrubbing the forums for a solution. To much distraction and a few tangential posts. Finally, I decided to ask if this relationship limit in Equipboard could be resolved to allow for improved listings. I recognize, this could go deep considering how many artists slide in for studio and stage work backing solo acts, but I would love that level of detail.

If there is a way, and I'm missing it, feel free to call me a dolt, but please do give guidance in the meantime.

Thanks,
