Ability to close/cancel an invoice while retaining a paid retainer

Hi! I have several shoots where the client paid a retainer through Stripe but later cancelled, ghosted, or never completed the session. Because a Stripe payment exists, I’m unable to delete the shoot or edit the invoice, which leaves the unpaid remaining balance showing as outstanding indefinitely.

I’d love an option to either:

* void/cancel the remaining balance
* mark the shoot as cancelled/closed while preserving the retainer payment history
Or
* archive the shoot without falsely marking the remaining balance as paid.

Thank you!
