Convert [H] to days, hours, minutes

Hey gang! I know about the 31 day limit and thus can't use a format to accomplish this. Is there a way I can easily convert the hours and minutes listed in column B into days, hours & minutes without having to manually do the math?

My end result would be to have a column chart showing each groups total. My director does not like having to figure out how many days the hours equal.

Thanks in advance
