Expressing metronome markings with different notes equalling beat

I would like to apologize if this belongs somewhere else, but I wasn't exactly sure where to put my question.
I was copying out a piece with a metronome marking of sixteenth note=126. I was wondering how to do this in MuseScore. The options on the palette only go up to eighth note. I tried copying and pasting a sixteenth note symbol from the internet, but that didn't work, with MuseScore displaying a Korean character. Is there any way to replicate the metronome marking I want? Thanks in advance.
