Haven't tried it; but stumbled across "Profiling()" function in the
HFWUtils package.
Starting at bottom of page 29-30 of HFWUtils package user manual:

profiling
plots tree of execution times

Description
determines how much time a function its and sub-functions (and
sub-functions thereof etc) take to run (‘profiling’). Also draws
picture of this using the interrelations of functions.

In a way I am looking for something similar to the
