Marking an invoice as paid pending cleared funds

Marking an invoice as paid pending cleared funds

I am trying to find a way to mark an invoice as having the payment sent, but still waiting to clear. I can see that invoices can be listed as "Payment Initiated" but I don't see any documents that explain what that is, nor can I find a way to assign that status to an invoice.

I want to be able to give my invoice a status between unpaid and paid.

Can anyone suggest any way to do this?

Thanks.
