Hi Michael, it is not clear to me what you mean by setting different physics-lists by region, as this is not possible. Regions can be assigned production-cuts, user-limits, field parameters... but not physics-lists. To set a different region for your daughters, you just need to set a new region and specify it as root logical volume (as specified in the documentation) once for the logical volume of your (parameterised) daughters.
