Alphauserpoints checkout workflow

Hi,

when using alphauserpoints as payment method (always only partially possible, rest of the sum has to be paid by bank...) the checkout progress advances somewhat like:

confirmation (without showing the deduction)
then a confirmation with the deduction
jumping to address
moving to payment
back to confirmation
...

It goes a little bit round and round.

I´d prefer:
confirmation with deduction shown
back to payment
confirmation with deduction shown
end

www.das-portal.at the site is online, if you need backend access I will send you a pm

Can I do that myself?

Best Regards
