I need to create a new payment module for Money Orders.
I need to add a step in between the select payment type and confirm order to display a message to the customer and have them print out an invoice and then display a require checkbox. 
Can I do think completely in my ps_moneyorder.php file or will I need to hack the virtuemart code?  If I can't do it in my ps_moneyorder.php file the way that I explained it, would there be another way I could go about it to where I could?  I don't want to hack the virtuemart code if I don't have to.
Any help or ideas would be greatly appreciated!
			
			
			
				So is this not something that is possible?
