Custom Note Lengths

[SkyriderRhythmic]

I know it's laid out in the Experiments tab with the chrome Dev tools, but instead of the drop-down menu, maybe have 2 windows where you can enter text. Something like
<enter a number>/<enter a number> I can see this being a bit rough to code though, so if it doesn't happen I can understand why.
Thank you,
