Is there any method to delay autoinvoice for RMA？

Expected Business ：
First:I booked a RMA.

Second:I receive the materials into the subinventory from the RMA.

Third:I want to note the Rma receipt this month,but I don't want to generate a credit memo in the same period.

Now,I don't want to generate a credit memo via autoinvoice for this RMA receipt during this month,and I want to autoinvoice in other month.It that means I want to delay Rma autoinvoice，and don‘t affect my generic business。
Is there any method applied to this business condition？

All help is appreciated.
