I do something similar but put shell commands as a comment, e.g.

    .\" set -eEu -o pipefail
    .\" f=foo
    .\" o='-p -t'
    .\" groff $o $f.tr | ps2pdf - $f.pdf
    .\" groff $o $f.tr | ps2pdf - $f-debug.pdf
    .\" exit 0

foo.tr is then run with something like

    sed s/...// | bash

I used to maintain a makefile and store what preprocessors were needed
for each file there, but I prefer this;  it keeps them with the source.
And being shell, it's highly flexible.

Cheers, Ralph.
