oil life maintenance report

I would like to add to the dynamic maintenance report - vehicles that are G6 geotab and can monitor oil life - have these specific vehicles show up on the report when the oil life is at 15% and less.  How do I do this?  I would also like to keep the same vehicles mentioned above on a millage basis for the report like the other vehicles, in case a driver resets the oil minder in the vehicle before the oil change is done.
