Priority of "show on fitness line"

Is there any way to “force” priority of which event “wins” in terms of colored dot on the fitness line, when there are several events that have checked “show on fitness line”?

e.g. I have an event that goes over more than a week which should show up on the line, but then in the same range also single day and two-to-three day events which should override the colored dot on the fitness line.

I’d be happy to do this on the API if that’s not easily done on the GUI. Something like an integer priority filed for that event that defaults to 0 (highest) and can be “downgraded” by increasing it would work for me.
