5/16 of 4/4 as a partial? How?

[Kenneth Wolcott]

Hi;

  I'm engraving a piece in 4/4 which has a partial of one sixteenth
note, followed by a dotted eighth and another sixteenth note.

How to engrave this?

My sloppy workaround was to use spacer notes (s2 s8.) to proceed the
aforementioned which completes the measure, but looks awful :-)

Thanks,
Ken Wolcott
