Calendar APP. trying to consolidate lines for a schedule

I'm trying to create an Install Schedule for our Field team. We have multiple items for One job site. See below. there are Multiple Installations going on for DH-Prickett. We don't need ALL these entries on the Install Schedule we would just need one line. Other than changing the underlying sheet to a parent child (I want to avoid that type of work on the user end) Is there a way to just schedule one line?
