How to manually, in server config JSONs, set the scav to PMC conversion rate?

On SPT 3.10, there was a setting in bot.json, I believe, that allowed you to set the percentage of scav spawns that would turn into PMCs, don't remember if it was "convertintopmcchance". Would appreciate any insight on where this setting moved to, has been reimplemented as, or if I am just blind, but VS code can't seem to find something related to "convert" in my SPT directory. Thank you

PresetBatch in bot.json seems to be the weights for all the bot types in the game, as least this is my observation with botUsec/botBear. Just do not set any type greater than 100
