Make multireddits not rely on reddit itself but on the device so you can have more than 100?

Idk if it's possible but the reason I ask is I have like 400 subs that are just all kinds of humor for me and about 200 that's just tech related and I'd really like to separate them without having multiple accounts. But it doesn't seem like it would so difficult or different to have a list on your device of subs that the device can fetch posts when you want it to then display them. Like I said idk if it's possible
