avoid role sign up drop down page with pageroute?

Hi , i was using your module , to create different membert types ,the case was , that i had 2 different buttons to register as different types of users , but if i use pageroute to autoassign a role id , the first time it forwards me to the drop down page , its there any way to avoid this page with the pageroute module?
(after selecting for the very first time the account type , and returning to the first page and then entering to another member type registration form , it automatically sets me the role desired)
:D thanks!
