FP&A Analyst to M&A Integration Manager --> possible future pigeonholing?

I am applying for internal move to M&A Integration Manager role.

The role itself looks very interesting but a cursory glance at people on linkedin with such roles seems to indicate that they stay in this function / move into more of a COO type position later on in their career.

Is this because its very specific type role?

Alternatives would be to push for promotion to FP&A manager maybe after 6-12 extra months instead....however without really performing any extra duties since the team is really small as it is and acting at manager level either way.

thanks for any replies / comments / views in advance
