Is there a way to bulk subscribe to all subreddits in a particular list programmatically (there is no built-in way to do this)

Currently the list is return-separated and " (break)" separated as well, but of course it could be in any other format such as csv. or whatever.

Hoping someone here could help me. I scoured google to try and find a solution but couldn't for the life of me, I must be missing something in my search! I'm surprised that nobody else would like this functionality.
