I think the automation to tell Tinderbox to activate a DEVONagent search agent or plugin might require a level of asynchronous interface that would be tricky to implement and test. Anyway, I suggest you write directly to Eastgate with your suggestion and explain the use case(s) you envision – context and purpose help when evaluating new feature suggestions.
FWIW, in the meanwhile, you might find this thread and the tool I posted there useful. The script still works.
