Hi Joann,
You can. But it requires the user who'll transfer the order to invoice access to the Type ID setup window that is assigned to where you transfer invoices.
If you look at the Sales Order Setup of the Type ID used for your Orders, there is a specified Invoice ID where the Order will use to transfer the invoices to.
If you pull up that Sales Invoice Setup, you'll see the Invoice ID Next Number, which is the one that will be used on your next transaction.
You'll need to have the use go though the setup information BEFORE they do the transfer.
It's quite tricky - but can be done.
