Added to consumer add: when prompting for subject filter(s) can parse the user input as a comma or space separated list of subject filters.

This is probably not [ADDED] but rather whatever we use to indicate fixed. Personally I dont really want those prefixes in this repo they dont add much value

Ok, just in the habit of using those prefixes because that's how they want it for the client libraries, but won't use them for this repo from now on.
