BIAB has quarter note = 120 ticks resolution, but only lets you enter up to 16th notes on the notation grid. If you can't play the notes in live from a keyboard (or can't import in MIDI or XML from a dedicated notation program), then what you can do is to enter two notes on the 16th note grid boundary and then manually edit their start and stop times.

At quarter = 120, that means a 32nd note is 15 ticks in duration. So on beat 1, the first 32nd note would from tick 0 to 14; the second from 15 to 29; the third from tick 30 to 44; etc. I would personally rather enter the notation with something like MuseScore (which is free) and then import the final result in rather than manually edit 32nd note durations.
