• [X] This proposal is a completely new feature. If you want to suggest an improvement or an enhancement, please use this template.

Describe the new feature

I've recently started using Windows 11 Dev Drives and I'm exploring relocating all my package manager caches to it. Based on what I've seen with the installer and settings, there exists no simple way outside of a symlink to do this.

I'd really appreciate the feature getting added and also the ability to support cache migration as well in the tool itself.

Describe how this new feature could help users

• Provide more control over placement of the cache folder.
• Introduce concept of system-wide vs per-user installation of packages depending on the user's needs.
