Hey @szymonnt,
Not right now. Content Control restricts content based on roles (as you’ve noticed). If you only need to restrict content to a few clients at a time, you can conceiveably create a custom role for each of those customers and then use that role in your restriction rule.
Examples:
Username: mickjagger
Role: micksrole
Username: jimihendrix
Role: jimisrole
Obviously, the username and role need to be one-to-one and this solution won’t scale up very well. But, it’ll work if you don’t need to scale very big.
Lastly, there are plugins like WooCommerce extensions (and others) that allow you to customize account pages.
We hope that helps.
Let us know if you need anything else.
Have a great day ??
