Yes, I agree. It would also be very helpful if you could define colours for a specific property to be the same on all reports on one dashboard.
e.g. property country: DE is always green, GB is always red, FR is always blue …
At the moment the colours are set automatically, depending on the values of the property in a view.
If report A has data for DE, ES, GB and IR
and report B has data for ES, FR, IR
ES and IR will have different colours in both reports.
