You can recreate a tuning page to be identical to BoP.
Choose your car and create 3 new default tuning pages and name them however you want, like BoP(H) / BoP(M) / BoP(L).
Then create a custom race go to these 3 tracks (these were daily races when BoP was split into 3) for the different BoP settings and adjust ECU down and weight up depending on the setup
Monza (any version) for Highspeed
Sainte-Croix Layout B for Medspeed
Willow Springs Street cours for Lowspeed
(for some cars, 2 of the settings are identical).
The car information in the center-top position is your currently selected car and its values (remember to have a default tuning page selected to compare for the changes)

The car information on the lower-right position is your current car with BoP adjustments

in this case it is ECU -7kw and ballast +39kg
Unfortunatly, you wont see which kind of BoP is enabled in the racing information (unlike in sport mode), but you can see it when you navigate to car settings
