Inserting New Measures

This seems to be about the best package out there. One seriously annoying problem - how to insert new blank bars into the music? Moving blocks of music around is a bitch, since everything has to be cut and pasted. Measures cannot be deleted with a single mouse click - all the notes have to be separately erased...aggghhh. Somebody please tell me if there are solutions here, or do I need to keep looking for another program?
