Hi @rifftual, this module PSDscResources is intended to be a feature compatible replacement of the in-box PSDesiredStateConfiguration resources. So only really bug fixes are made to this module. For enhancements to the module, recommend logging this with the community version of the module: xPSDesiredStateConfiguration: https://github.com/dsccommunity/xPSDesiredStateConfiguration/issues

Apologies for the delay in getting back to this.
