is it possible to add a set amount of time to every run set in the category? id prefer not to have to manually do that

i play a racing game, where the speedrun would be across multiple maps with an ingame timer. is there some sort of 3rd party thing that could automatically collect those times? i dont wanna include loadtimes/menuing, but also dont wanna have to write down the times

i presume emulator is allowed? i want to ask cuz i dont see any emulator runs on the leaderboard, but also dont see any rules against it. the emulator is mostly fine, there are some known graphical issues though
