RS logix 500, program "Flow" Checking

In RS Logix500 (with ML1100) I am developing a program with a lot of program files used as sub-routines that are called as needed. Is there a way of looking at the program structure so I can easily see if part of it is being called or not. I am thinking of a similar way to what you can do in S5.

Its a shame the JSR command does not go green if it is called

I hope this makes sense.

If the JSR instruction is conditional then the condition upstream of it will be green.
You could put a self resetting timer in the subroutine and watch it time.
Or an unconditional add instruction in the subroutine and watch it increment each time the routine is scanned ( make sure it is reset to zero before an over range occurs).
