Gap Night Trigger for EITHER Arrival Gap or Departure Gap and coordinating field code

I would like to set up a gap night offer trigger where if the arrival gap OR departure gap are 'less than or equal to 2 nights' then I can send the renter an email with a field code similar to {BADJOPEN}. However, currently the only way to set this up requires that if either arrival or departure gap meet the requirements, then both dates are sent to the renter even if one of the gaps is more than 2 nights and that is not good. 

This means that I cannot use this automatic trigger right now as is and instead have to manually run a gap report and send email templates to guests, modifying the dates for each before sending. 

I would like to request that either a unique kind of trigger be allowed for this scenario or a separate field code be designed to reflect the trigger itself, not just for both leading and trailing gap nights.
