Please make it possible to play custom games solo as a survivor

There is no way to practice or gain map knowledge as a survivor. You cannot start a custom game with 0 killer(s) and there are no killer bots outside the one in the tutorial. I know that implementing a bot for any or every killer is not a simple thing but all i need is to be able to enter a map as a survivor alone to practice certain vaults, routes etc or just warm up even. The only way to do this right now aside from having a friend join is to have another pc with another dbd account logged in to load in your custom game and that is just not right. Please let there be a way for survivors to load in and practice empty maps I dont care if it has a killer bot that just sits there and does nothing (i would actually prefer this) all i need is to enter and explore and learn maps freely.
