Help with Courtesy Tone (Roger Beep)

Anyone else ??? Anyone else have any ideas ? We have people who are trying to get in the repeater but are barely breaking squelch. But just keep on talking. So every time the squelch gets them, the roger beep , beeps. So in a 10 second speech, the roger beep may go off 6 times, yall can understand how annoying this must get.
