That field is implemented as an integer in the database, and there are many assumptions throughout all of the code that it is an integer. It would not be trivial to allow it to be used for text values as well. I might suggest you use a different field like Source Type if you have that requirement, as could add a 1-15 and all of the letter combinations you listed if you use that field instead.
