[Scopes] Execute command in specific scope

Question

Hello fellow Powershell users,
I am currently looking for a way to execute a command in a specific scope of my choice. While some commands offer a choice in how they do that, many do not. Any ideas on how to do this?
Background:
I occasionally find it useful or necessary to affect items on another scope. With Variables that's not an issue, but with items like Aliases or Functions that's not quite as simple, since the standard provider cmdlets only appear to work within the current
scope (And that allscope option on Aliases is a joke - you can remove-item them all day long without affecting them in a parent scope, which es exactly what the documentation suggests should work).
That situation got me thinking, and knowing generally on how to do this would be great.
Cheers,
Fred

Hi Matt,
sure I can:
Remove-Item Alias:\ri
This will delete the Alias from the current scope, but not globally. I know of no way to specify scope on PSDrive stored variables and functions / commands will by default affect content in the current scope (yeah, I was a bit inprecise in my
terminology there).
The concrete mater at hand is that I'm busy writing a module that creates extended Aliases (Predefined parameters, added aliases for parameters, constrained Validate-Sets ... stuff like that). So I'm trying to implement a Force parameter that will replace
current aliases with the "new one" (I actually compile it as a function and real Aliases take precedence over functions ... and any changes I make to the aliases revert once the command ends and the user returns to the parent scope).
Anyway, since I don't want to be fighting that same battle the next time I have trouble with scopes, I got wondering whether there's a way to choose on the function side which scope it affects, instead of finding an individual way each time a problem occurs...
Cheers,
Fred
