Client Portal - mark as paid via bank tansfer

Client Portal - mark as paid via bank tansfer

Is there any way that clients can mark their invoices as paid by 'Bank Transfer' within the clients portal?

At the moment when clients log into their client portal and select "Pay Now" the only option is for them to pay by card.  What we would like is the options for our clients to tell us that they have paid this invoice by 'bank transfer' or 'cheque'

Thanks
