Attach parameters to linked objects
There are times when it would be very helpful to attach a parameter, or a set of parameters to a linked model - it addresses situations where multiple consultants have scope related to the same object.
for example - as security system consultants, we often have scope related to doors. The doors themselves, and the bulk of the hardware are the Architects scope, and installed by the carpenter. But card readers, request to exit devices, sensors, etc fall into the security scope, and get installed by a security integrator. I can tag the doors to show the door number, but it would be fantastic if I could attach at least one separate parameter to the doors with a security device set.
Part of this is because I cannot copy/monitor doors - but I think it would be simpler if I could simply say "this thing in your scope also has this impact in my scope."
