single triplet note with some indication?

[Nick Didkovsky]

Hello,

If I have a single not that is a tuplet I would like it to show some 
indication of what tuplet it is (for ex a "3" over or under it).

For example, if I have a passage of music which contains 2 eighth note 
triplets followed by a straight quarter note, followed by the single 
eighth note triplet, I would like the final note to show that it is a 
triplet

Thanks,
Nick Didkovsky
