OK, you have an *explicit* echo, and you want to add some more
information to it by hand?  You don't want the shell to output
information automatically, as I assumed?

You can output the information from $PS4 by using "print -P".  So for
example

print -P $PS4 Got to this bit.

Prompt sequences are expanded but anything else is printed as normal.
