Pretty sure it's possible or there are other options. But you'd probably had to invest a lot of work and time to make it work.
For most people it isn't worth the effort, which I understand.
I think it'll take some time until these apps become that andvanced. Most lemmy apps are in a pretty early stage of developement and still highly WIP.
Some third party reddit apps seem to be planning on moving to lemmy, so maybe we'll see something better coming around the corner in the near future.
Get out of my mind!
