Limit seats per user

The plugin already provides an awesome functionality to limit the number of seats per event based on the email. That is really good but I found it easy to skip the restriction in my scenario if you just provide another email during the booking process.

I’m using seatreg on a website where users need to be registered.

Could you please help using the same functionality but instead of being based on the registration email, being for example based on the current wordpress user id?

I would really appreciate your help on this one.

Thanks in advance!
