Aliases for DRI connectors?

I'm searching for some sort of scheme that will let my DRI master query the set of available connectors and select the one carrying a prearranged designation. The problem I'm trying to solve is to allow deploying one standardized userspace component across a fleet of devices that have varying numbers of displays, with the use cases not always driven on the same connector topologically.

I had a look around the properties available on my system's DRI connectors, and nothing immediate jumped out at me. Is there a standard connector property that (assuming I can find the right place in DeviceTree or similar to) that would be a good fit for this?
