Query regarding CTC Revision

TCS hired me as a fresher (Digital) as it was campus placement hence the CTC was based on that. But they took time to send Joining Letter till then I worked somewhere else and now I have 2+ years of work experience which I have updated in my GESS/Digital Profile. Is there any possible way to get my CTC revised according to my experience?

I have already completed 5 months and In my current project, I am hired as an experienced designer. I have my last employment CTC letter with me. Is there any way TCS can match that?

Can anyone help me with this or tell me the POC?
