We apply the following glob patterns to pick up catalog or parameters references

python
conf_catalog = conf_loader.get('catalog*', 'catalog*/**')
conf_params = conf_loader.get('**/parameters.yml')

Oh actually as I write this I realise you can only do that for catalog as we enforce the

.yml

name for paramters

So to answer your question - I think you need to inherit and override the default config loader class, change this

conf_params

argument and then register that configloader in hooks.py
