Multiple check formats for bank account under payment document

Hi,

The customer uses both crossed and normal checks from a particular bank account.

I have developed separate PPP , formats , templates for both these formats.

Since same check number sequence will be used from this bank account for both crossed check and normal check I need to provide the option to select the relevant format at the  payment window.

However under payment document tab of the bank account there is only one option to select the format.

How can I achieve the same!

Regards
