Am I able to customize my **GIFT Receipts** ? Three Questions

[lakeboutique]

I am only able to customize my regular receipts, but I need to print my return policy on my gift receipts as well.

Is this an option?

2. I am able to process one exchange for an order, and then if a customer would like to exchange again from the same order, it will not process a second exchange, 

Can someone tell me why? or how to get around this?

3. We have added customers in our system more than once, is there a way to combine them? If it's the same name?
