Importing Raw Files When Not Connected - Best Practices

I currently use LR Classic on my desktop at home, connected to an external with all Raw files - and then use Smart previews and a catalog on an external so I can edit and export on my laptop when not at home. When I get back, everything syncs up. I usually import Raw files directly into my desktop system and build previews on import. Works great for me.

My question is, what if I wanted to import Raw files while I am outside my home? To reiterate, I want to get the Raw files into my current workflow / LR Ecosystem when I am not on my desktop, and not connected to my Raw Files external drive.

How would one go about doing this?

Thanks to anyone who can help me out here !
