Syncing albums between my phone and Immich

I have about 14,000 images and videos on my phone, and so I usually navigate my gallery using albums since it just isn't practical to find a specific image in all that. Because of this I use albums to organise everything so I know where to look for a specific item.

I noticed that Immich creates albums on the app to correlate with the albums you're uploading. However when I tried this for my whole gallery, pretty much all of the albums on my phone were then created on Immich, and yet they all seem to be empty. Also, my recents folder (which has all 14,000 images) only contains 1,700 images.

Ideally, I would like to find a way of uploading all my albums so they're in the same format as on my phone, and then upload anything else that isn't in a folder aswell. However I think Immich doesn't tend to like duplicates, and there are some photos on my phone that are in multiple albums.

I know that this is just a backup solution, so I'm not really that bothered about it if I just have to upload all the photos in one collection and then just have an album named "Phone photos" or something. Guaranteed if my phone dies and I lose all the data on it, having everything organised into folders won't be my biggest concern.

Just wondering if this is a possibility, because if it is I'll do it that way instead.

Thanks!
