For your application you may want to try Realband instead. It comes with BiaB if you have a recent version.

It has a very nice editor, abd can remove all the extra data in one shot if you want.

It is called Event Editor and there is a checkbox for 'use data filter' which will allow you to only remove the items you want from any track.

Also the tracks will open a regular tracks without any 'Melody' association and such.
Just an idea..
Also this should be posted in Off-Topic for best response, as this section is for giving tips learned along the way.
