Hopefully a simple question.

Using the Rule Editor, I can open a routing rule and easily define an 'effectiveBegin' and 'effectiveEnd' date.  I want to utilize this date feature for a "sub-rule" (i.e. rule #1) but not the entire routing rule therefore impacting all other rules. I also do not want to split and create a brand new routine rule just to send the message to the target business process.  It would be ideal to keep it contained within this single routing class that was created.
