More granular Connector and IdentitySource settings through Powershell

We want to be able to go to Connectors -> Setup Store Connector -> Release: Publish to Production. By Default it's set to Development when we create this connector through Powershell. Also we want to be able to go to IdentitySource -> Contacts to set correct Group through Powershell. Would be nice to have all the possibilities that's in the GUI also in Powershell. Thanks!
