Custom Widget - not autoscale to same Y-axis scale for all values?

Hey there,
Is there no chance to have the same Y-axis scale for a custiom widget AND autoscale?

Background:
I have an ESS and want to display the grid power for the 3 phases in a custom widget.
If I do nothing, each signal has its own scale.
If I select custom, I can only select fixed min/max and then details are lost.

Is there any chance or are there any plans to do so?

Thanks
S.
