Tracking Meter Readings in Sage 300 CRE 15.1

I'm trying to set up Equipment to monitor service records for our equipment - primarily oil changes.  When I use the Meter/Odometer it just overwrites the last entry.  I need to see Equip/Date of Last Service/Mileage(Meter reading) at last service/Current Date/Current Mileage(Meter Reading).  I have worked with Misc Entries and can get the information in but I loose the "last date/service" in reports.  Help? 

This is in an excel worksheet - but I would like to be able to track this in Sage.  The "Since Last Service" is just a calculation.
