Set FCPX play rate to 1.25x, 1.5x, 1.75x

Is there a way to set the playback of the timeline to a play rate of 1.25x, 1.5x, or 1.75x?

By pressing L the play rate jumps to 2x, additional presses can jump it to 4x, 8x, 16x, and 32x. These other faster rates can also be assigned custom keyboard shortcuts. But for content review, I need between 1x and 2x playback rate. The faster rates are fine for skimming through content but not as helpful for critical review.

In Quicktime 7 Pro, you are able to press command k, and then adjust the playback speed slider to ramp to the rate you want for content review. In QuickTime X, this feature is broken where no audio is played back faster than 1x. Quicktime X does play audio backwards with the media when the J key is pressed so L key missing audio going forward certainly smells like bug.

With FCPX workflow support now enhanced and better Frame.io integration, having better control over the playback rate would be incredibly helpful but I can't for the life of me figure out if there is option in here somewhere to have finer controls for speeds between 1x and 2x similar to how the clip speed can be changed to a custom rate outside of the predefined rates.

thanks for any help.
