On a component, I would like to manage special data Quality overlay in replacement of built-in Ignition data Quality overlay.

When I disable quality on the component bindings with the Overlay opt-out checked, the data Quality property is forced to 192.

I would like to keep the data Quality property calculated and use it for example to bind to the background property.  
Is there a way to do this, project properties ? to ignore Quality build-in overlay but to keep data quality calculated (not forced to 192) ???

I known it is possible to redo the calculation of the data quality but it is not very convenient.
