Again if you read the help: 
    When two universal prefix arguments, only tangle blocks for the tangle file of the block at point.
So if you give two universal prefix arguments and issue org-babel-tangle while you are at a code block with the tangle file /home/zeltak/.i3/config, it will only tangle code blocks with that particular code block. I think that is what you want. I'm sure you can modify the code I showed you to implement this.
Another way to do this is just `org-narrow-to-subtree` to narrow down to that subtree and and then just tangle the whole thing.

You can `:tangle no' on the source block to exclude it from tangling.



You can even tangle one source block to a different or as many files

as you like during tangling.
