Promotion Outside TD - Is possible?

Thats bassicaly my question. I’m from Argentina, We are going through this Talent Discussions period and my PL said to me that I was the best L11 in that TD, a lot of people said great things about me and according to him even the director said I deserved to be upleveled to L10 but other people (L11 as well) has been expecting the promotion for longer time and as I’ve been in accenture for only 8 months they were going to make me wait for the next TD on April next year. I understand the situation but my question is: Is it possible or there are cases where you can be promoted outside the TD process? Because I think it’s kind of unfair to be put on hold when I’m working 9hs a day and puting my best. obviously I’ll recieve the performance bonus but still. What do you guys think? Should I claim something here? After this the idea of start looking for new jobs its rising on me if this situation may happen a lot…
