SM-N910F ROMs with Fixed APN Types

I have tried many of the Snapdragon ROMs for the 910F phone. Most of them that are TW based have only three possible settings for the APN Type (Internet, MMS or Internet + MMS). The CM based ROMs have a user enter-able field. My phones MMS works on the CM based ROMs because it has the proper APN TYPEs.

It would be really great if the TW ROM makers would change the APN Type to allow this field to be manually entered.
