Is it permissible to break off the first congregation if one joins it at the end, in order to join a second congregation and attain the virtue of the congregation?

Question:
If a person joins the imam in prayer and the imam is in the final tashahhud, and then you find a congregation, if you find another congregation, is it permissible for this person to break off the prayer he is in and join the second congregation to attain the virtue of the congregation?

Answer:
Breaking off does not mean he abandons it; rather, he completes it as a voluntary prayer, shortens it, says the taslim, and joins the congregation. Yes.
