that's relatively easy to do in code, except making the settings for that would be a nightmare.
So, for this add-on it won't be added.
The correct solution to your issue is Adaptive playback.
Where the quality automatically switches depending on your internet speed.
The add-on uses Inputstream Adaptive which doesn't currently support Adaptive playback.
However, there was a GSOC for 2020 for that so hopefully it adds it in soon (soon as in next few months)
In the meantime, if you change Quality to Bypass - IA should choose the initial quality based on your current download speed.
With Bypass, you can still use Context menu to force a quality.
