one time view: registration possible for revisiting users to view once paid content on page

Hi,

Payment Option "One time view" allows for paying to view content without registration. Authorization appears to be Cookie-based.

Is it possible to allow a buyer to optionally register for "One time view" content so that he/she can view the purchased content any time later (without Cookie)? This registration should allow access to the one piece of content purchased only.

If not, can you add such a feature?

Thank you very much!
