Really depends on how the post is outputting the rotary.
You probably want to output it in the ptlchg section of the post, after the tool is called ( pbld, n, *t, "M06", e). Somewhere after that you should add a line to force the rotary pbld, n, *cabs, e (or what ever variable is calling the rotary output.
Of course you didn't say it it's V8, V9, or X. so this format will vary slightly.
