[GNC] How to delete multiple payments & posted bills?

[Fran_3]

BizA had an issue with VendorX and needs to delete most of VendorX's posted bills & associated payments.
We can go in and...
- delete each individual payment one at a time

- then un-post each individual bill one at a time

- then delete each individual bill one at a time
But... is there any way to...
- delete all the appropriate payments at once
- and then delete all the appropriate posted bills at once
- without having to do each and every one individually?

Thanks for any help - Fran3
