Last minute (less than 30 days) reservations customizations

I use Pricelabs and I have it set up to allow 6 night and 4 night min stays within certain last minute parameters (20 days before or 15 days before). During these last minute times, I want to allow any check in day or departure day available. The problem with setting up my seasons to do this, is I only want Saturday to Saturday during prime time, unless its last minute. How do I set this up? I see where I can state Saturday check in and all days of the week as check out but I don't see how I can customize arrival day only for these last minute dates.

There's not a way to set dynamic arrival/departure day rules based on days from now criteria.

We do have an update in the works that will add arrival/departure day rules to the individual nightly rate calendar -- once that's in place you'll be able to have PriceLabs push those rules from their side. No ETA yet, but hopefully by year end.
