You can do that already.

You can create an Alby Account.

Then you install "Alby Hub" on your node. (Available on Umbrel and Start9 and Raspiblitz, that I know)

Then you connect your Alby Hub to your Alby Account.

And then you can create sub-accounts which are labeled as family and friend accounts. Which is really nice.

But my post above was about lightning addresses for these sub accounts. It would be awesome if there would be a way that eve y subaccount could get a lightning addresses like "blabla@getalby.com" That would improve UX for newbies a lot.
