I personally use two specific options in the debug menu. The 'generate egg in daycare' option and the 'set eggsteps to 1' option. I still have to put the right pokemon and items in the daycare, as well as getting the right stats and genders on the babies and do all the other steps, but I just skip the generating and hatching parts, which are the most time consuming ones. I personally dont feel like wasting time waiting and running the same path 300 times.
