Field One - Linking Agreement(s)

I am curious about the ability to link Field One Agreements to Entities other than serviceable assets. I have a custom entity called "Locations" providing us with a way to identify rooms/floors/building/etc. under the Service Account entity. Ideally, I would like to link/attach our service agreements to specific rooms we are supporting.

Environment: MS CRM 2016 On-Prem

Thanks,

Michael
