Any way to search multiple MultiTerm termbases, while having only hits from a single termbase shown in Term Recognition pane?

Is there any way to search multiple MultiTerm termbases, while having only hits from a single termbase shown in the Term Recognition pane? This would be very useful for me because, although I do not want to have all of my termbases connected because this would clutter up the Term recognition window with useless hits, I would like to be able to quickly search them all while translating.

The same question applies to using Excel files as termbases (via "Excel-based terminology provider"). Would it be possible in this case?
