RULES ENGINE FOR LAB RESULTS THAT DON'T COME BACK ON SAME DAY

AR closes accounts 2-3; this is a problem for our Laboratory department when patients have lab tests that either get sent out with a 2-5 day result turn around, and/or other tests that take time to grow for resulting; a rules engine to allow some charts to stay open and allow the others to close for proper charge capture would be something we'd appreciate, if at all possible.
