Tremolo in odd meter

Hello!! How can I make a tremolo between those two notes in this particular meter?
Thank you very much in advance!

I believe you’ll need to separate this into two tremolos, one for the duration of the first beat and one for the second. Thus, you will need a two-dotted-sixteenths tremolo followed by a two-sixteenths tremolo.
