I've just sent you a private email requesting this functionality and have stumbled across a number of support requests (a couple of years old) asking for the same.
As a paying customer of the 'pro' version, I would love to see this added, thus I would be able to add your plugin to a number of other sites I manage.
A great plugin yet I feel you are missing out on a lot of business by not having CPT support.
Hopefully one to add for upcoming versions?
Keep up the good work, stay safe!
