Just give the Race Director a heads up at the “drivers meeting”. He’ll likely give competitors in your race group a heads up to allow you to go to the front of the scale line after your race. Also have someone willing to stay in post race tech with your kart if you finish in the top five.
You can also help by having someone get your second kart to the grid, in position, ready to go. So all you have to do is hop in and go.
