"Teams who share a pc, will have to stop at the designated spot in the pits to perform their driver swaps, there will be a minimum time that they must spend in the box"
I dont understand how you are struggling with this, I will try to simplify......
Team comes into pits, stops at designated spot for driver swap, waits for the required time stated by staff and then drives out of the pits.
Race finishes, team owner sends me pm stating which laps they made there driver swaps on.
with 12hrs, I look through the replay to see if the swaps were as described and within the rules.
5 mins later, I contact team owner to inform him everything was fine, or I tell him they broke the rules and they got a D.Q
*Simples*
