Tantumergo is a very wise man.
This is not a tribunal issue; it is an RCIA issue.
RCIA involves catechetical instruction, with formal rites of the Church intervening, such as the Rite of Acceptance after the initial Inquiry, then the Catechumenate, then Mystogogia, culminating in the Rite of Full Acceptance. There are timeframes surrounding each of these steps in the RCIA.
What I would recommend is that you ask the pastor or the director of the RCIA program if you could just attend the sessions. You would likely have to attend them again, once your annulment becomes final, but you'd then have an even deeper knowledge of the Faith before you made your Final Profession.
Someone should have explained this to you, and invited you to attend the sessions anyway.
