Gradual Tempo Change - setting final tempo

Entering gradual tempo changes like accel. & rit. etc into the music is very straightforward in Dorico but I can’t work out how to set the final tempo for playback. There’s a box in the property panel that says “Final tempo %” but it seems to be permanently greyed out.

Is this yet to be implemented, or is there some other thing I should be doing?

I’ve been wondering about this myself - I’ve looked around in menus and in Play mode, and can’t find anything.

You can’t set this, I’m afraid, Stephen, but it is planned for the near future.

Thanks Daniel.
Now have a rest from the Forum & go & put the sprouts on!
