Custom PO Print in iSupplier

Hi,

I have a custom PO print that is based on a custom data definition/template. We don't use the seeded data definition and templates. My question is, is there a way our suppliers can access this custom PO print directly in iSupplier portal?

A potential workaround in my mind is to attach the custom PO print to the PO header as an attachment and then let supplier users access is from iSupplier portal against the specific PO, however i want to keep this as my last option.  Are there any other solutions/ideas? Please advise/help.

Thanks,

Nitin
