Tempo equation: quarter note to eight triplet note

is it possible?
I need the playback to follow this tempo equaton, but seems I can’t use the function available to combine triplets and quarter eight notes.
Any hints?

Dorico doesn’t currently support tempo equations that contain tuplets. For that, you could use a system-attached text item and a third-party font, such as Metrico.

If necessary, you can add an equivalent immediate tempo mark at the same position and hide it.

Ok, thank you!
