Save Album to ext. storage - but have it still available // Keep Album in LR CC but not in Cloud

Alright folks, I need to ask. I just don't find the right solution online.

WHAT DO I LOOK FOR?

1.) Outsource a specific album

As I do in Premiere Pro with whole projects, I want to transfer special albums to an external drive. Then I want to have the possibility to go that ext. drive, select that particular album incl. all the files and settings and do some further work within LR CC. So that I outsource particular 'high volume' albums to my ext. drive and still have the permanent possibility to enter them by plugging in my ext. drive. But I just dont see a way to do so. In Premiere Pro I just copy the whole project folder to the ext. drive and that's it - that's what I want to do as well within LR CC.

2.) Separate an album from the cloud

Seperate a specific album from the cloud. I mostly don't need the albums in the cloud so I thought there might be like a button or sth. which allows me to decide whether I want to connect the album with the cloud or not. Simple as that.

So what do u think? Any help?

All the best.
