Spare sorting in worksheet view

I have multiple fixture types, each type has spares.  The spares have Spare as the position and the purpose, no unit number or address.  Some fixture types the spares end up at the beginning, some at the end, some in the middle.   The one that's in the middle I think the ones that are after it were either added or changed from a different type, but they are the same type now so it shouldn't matter.  I am trying to figure out how to get the spares to the end of the list when I print the labels.  also and I don't think this matters, but some of the empty Unit#/add have  ---- and some are actually blank.

Thanks, Chuck
