Metric modulation triplet = eight note?

Hello,

is it possible to define a tempo relationship that includes triplet on one side?
Example:
triplet eight note = eight note.
The list of Tempo popovers doesn’t include this.

Thanks

Not natively, but Florian Kretlow has developed a free font called Metrico precisely for these purposes. See https://www.steinberg.net/forums/viewtopic.php?f=246&t=151856&hilit=Metrico#p817178
