Ability to Associate Mobile App Auto LifeCycle Metrics with custom vars and props

[#1]

We cannot associate LifeCycle metrics with standard vars and props that are important for use in a roll up secondary report suite. We use vars for brand and app name rollups in the secondary report suite but some LifeCycle metrics are not associated with these vars this creates a large bucket of metrics that are not associated with the brand or app name in the secondary report suite making meaningfull roll up views of this data impossible.
