Parkings Table in Group of Drivers

Hello,
I new client has requested the parking tables by group of drivers.

Problem:
Client wants to control the parkings above 30 minutes of the drivers, but separeted by drivers, as they're controlling the working hours.

Solution:
Create a new table inside of group of drivers that already exists with units/group of units: Parkings. Also add the same filters.
This is very important for them, because in group of units the parkings from diferent drivers are mixed inside every vehicle.
