Feature request and upgrade

Hi,

Thanks for contacting us here about this extension.

I am looking for a download plugin that punches btw. inserts the buyer's email address into the downloaded PDF. Does this already exist or is it expected that this function will be retrofitted?

This feature should be customized or use 3rd party plugin.

If I buy a plugin now, can I upgrade to the bundle and just pay the difference?

Yes, you can upgrade to a higher package while your subscription is valid. The deduction will be applied automatically while renewing corresponding your usage of the current license.

Thanks a lot!
Cheers,
