Firefox Monitor and local-parted emails

Firefox Monitor has a limit on the number of monitored email addresses (15). However, I use the "+" symbol to register on sites - just to determine which site caused the leak. That is, email@mail.com and email+forum@mail.com are the same email address. I have hundreds of such modified addresses. However, the Firefox Monitor allows you to track only 15 of them. Is it possible to remove the limit on the number of addresses served, or make the FM perceive email@mail.com and email+forum@mail.com (etc.) as one address?
