Can u create an invoice directly from a potential?

Can u create an invoice directly from a potential?

When i'm viewing a potential i cannot seem to create an invoice straight from within it. I have to create a sales order first then create the invoice from that. I'd rather not have to do this every time I want to raise an invoice.

Can someone confirm that it is possible to create an invoice straight from a potential, if it is possible how do you do it?

Regards
