SELECT_BY_REGEX Case insensitive possible?

Does anyone know if REGEX in Appgyver supports case insensitive matching? I tried the /i flag but it doesn’t work. Specifically I’m using SELECT_BY_REGEX to filter based on variables

SELECT_BY_REGEX(data.mylist, pageVars.searchField, pageVars.searchText)

This works great but I’d like the match to be case insensitive if possible.
