Please recognize 1st, 2nd etc with superscript

Hi! We are loving this plugin, thank you so much. We have some Bible notes where 1st, 2nd (Chronicles/Peter/Corinthians, etc) have the “st” or “nd” in superscript letters. When this happens reftagger does not recognize the Bible verse and I am having to edit them to appear as a normal “1st” or just “1”. If it’s at all possible to allow these characters to be recognized, that would be really great!
