Setting custom scale using integer instead of slider

Hello,
I’m wondering if you’d consider adding extra functionality to the Custom Scale option?
My internet caps out at roughly 12MB/s, but the closest the Slider will allow me is either 5MB/s or 20MB/s. That’s quite a large jump and either wastes screen real-estate or I cannot see the full extent of the graph.
It would be handy to be able to input my desired Scale Size using numbers so I can dial in for my optimal graphing range.

Cheers,
iisacc.

Thanks for your feedback in allowing number insertion for custom scaling.
