absolutely. It should be relatively easy to copy a string e.g. a filename from an actual file or a rigname/recordname into a new column (tag) when a new record is inserted into RMs database - no matter whether this happens by importing a rig from a file or by copying a rig that is already present.
A simple "click" on that column's header and the sorted table would reveal which source rigs/files have been spreading their sonic genes.
But I am also totally biased as to what I consider "simple" and "useful"; e.g. I have absolutely no need for a metronome in the Kemper - I have always access to the one on my iphone and I frequently use a "bodybeat" and whenever I record I use a click track or a drum pattern. So why spend the limited programming resources of the company to re-invent the wheel? But this is my personal view/preference. Many other users seem to believe this feature would be very useful.
I usually do not post in feature requests sections anymore, because everyone always likes his own ideas and on many occasions you will get fire or at least a touch of negativity attached to how you are perceived by the community, if you somehow argue "against" an idea. No matter how rational or logical the arguments are, emotionally you put the idea down and usually people feel put down or attacked if you "argue" against their ideas.
The need of a double finder can be prevented by a few basic rules/principles that you keep following when you are working/messing with rigs. That is all I wanted to say.
