Aux fan during bridge line

Hello,
Is it possible to set the aux fan to run only during bridges?
I am trying to print PLA with a 0.8 mm nozzle. I’ve tried changing bridge direction and speed already. I assume cooling is causing issues with my bridges.

In the past, I’ve had plate adhesion issues with the aux fan running all the time, so I’d like to set it only for bridges if possible.
Thanks
