Hi Ivan,
There isn't a built in way to use the existing favorites functionality to favorite a record specifically but I have often build a favorites report with a filter for a favorite checkbox that I created in my records for Admin use. Then I can add that specific report to my favorites using the built in options. That way I can favorite any specific records I am working on by checking that box and then when I'm done with them I can just uncheck it and drop them off my report. This can work with a common favorites report or a personal favorites report. I hope this work around suggestion is helpful Ivan.
If being able to favorite a record using our existing favorite functionality would be helpful to you I would also suggest giving us that feedback on User Voice. User Voice is the tool our product team uses to track customer interest in new features and enhancements to our existing features like this. The Quick Base User voice can most easily be accessed from the My Apps page in Quick Base by clicking on the orange Feedback tab that appears on the right of the page or at
http://quickbase.uservoice.com by signing in with your Quick Base credentials.
