I guess it is for @j.jaffeux to decide, not sure if that fits at all with the current UI we have? I am also not sure normal people want to type that much versus click especially on a smartphone?
It makes sense in google calendar because you can do this while typing in the name of the event, e.g. instead of typing
“Plumber”
you type
“Plumber 3pm - 5pm”
but that’s easy because I am on a device with a keyboard.
