I still dearly want this as well. We have a plan for a new addressing system that would allow for an unlimited number of Control IDs (functioning more like OSC addresses), but we haven't been able to implement it yet.
Once Control IDs can be unique, it'll allow moving bits of Control Panels between patches and sharing User Actors with paired Control Panels without the possibility of causing a conflict, which I really look forward to.
One way you could store and recall more info at the moment would be leaning on the Data Array actor or using the method outlined in my previous post.
