How can I keep Midi regions from changing their name to the name of the track I'm moving it to?

How can I keep Midi regions from changing their name to the name of the track I’m moving it to?
Say, I’m dragging a region with the name “trombone” to a track below, which has the name “Midi 1”, the region’s name changes to “Midi 1”. Is there a way to retain the “trombone” name on that region? Perhaps a modifier?

Cheers

I think there’s an option in the preferences. “Part takes Track name” seems to sound familiar.
