thank you, I will have a look at the Character bones thing.
and sd-webui-controlnet has an API that allows you to target individual ControlNet models:
https://github.com/Mikubill/sd-webui-controlnet/wiki/API
example is here: https://github.com/Mikubill/sd-webui-controlnet/blob/main/scripts/api.py
unfortunately that's for the API to standalone applications and not for scripts. There is a bit of a hacky way discussed on GitHub for allowing multiple controlnet layers to be controlled independently with a script, but I haven't tested it and I expect native support for it will be officially added soon enough anyway
