Ok I just tested my idea and it does work ... kinda.
If you record at least one take. setup punch recording and start recording before the punch in it does not mute the lead in portion of the previous take.
If you want several takes of the punch section just setup loop points that are larger than the punch in section. Then you can hit that once section over and over with the lead in as long as you need to get comfortable before each take.
So you can have your cake a eat it too if I understand what the OP is wanting to do.
