Sorry, last I checked, there is no sender-based routing support in sendmail. You cannot even try to create rulesets to get that.
Looks like it is my turn to eat humble pie. You will need to rebuild sendmail.cf after applying this hack.

For those that might be interested I have found one other alternative called Smart Table available at:

However it is for sendmail 8.5+ and will not work with my 8.13.
I have also found some documentation for both at:
