Option in garage to autoupgrade lower tier vehicles.

After hitting the vehicle cap, I want to upgrade all tier 1 vehicles to tier 2, and likewise for tier 2 to tier 3, etc.
Right now each vehicle needs to be manually told to go get upgraded. It would be nice to have a single button in the garage to allow auto-upgrading of vehicles. Perhaps by type (i.e. auto-upgrade shovels, or auto-upgrade trucks)

Mega trucks can't carry components, so maybe an auto-upgrade just to tier two
