[ Request] add `apt-mark hold` equivalent

[K-mikaZ]

Sorry for my English.

I have some programs installed (without scoop) and when I do list (local), they detect them anyway.

For example, I would like to make an apt-mark hold $relevantApp, to be able to do an update *, without scoop supporting these programs (instead of doing update * --except long list of application).

I hope I have been clear enough.

I'm not sure how is this even possible for scoop to list apps that it did not install. The list command does Get-ChildItem $dir on the scoop apps dir. If you did not install your apps into the scoop dir (which you should not) they won't be either listed or updated.
