Manage User Specific PowerShell Functions in Active Directory Domain

Question

Given: Windows Server 2012 R2 / PowerShell 4

Do need: a way to manage user/role specific PowerShell functions in an Active Directory domain.

Do NOT need: help with coding these scripts. This question is about managing user/role specific PowerShell functions.

An example:

1. Developer logs on to his workstation
2. Opens PowerShell
3. Issues a command Start-RemoteDebugger
4. msvsmon.exe starts on his workstation

Another example:

1. Developers opens a remote PowerShell tab to test server
2. Issues a command Start-RemoteDebugger
3. msvsmon.exe starts on the test server

What would be the best practises in managing such scripts? Given that only specific users/roles can actually write these scripts.
