We've published a new demo: Change element text alignment in inspector
How to configure an inspector field to control multiple attributes at once? One option is to define a custom element which binds a high-level attribute (textAlignment) to multiple presentation attributes (textAnchor, textVerticalAnchor. x, y).
Here is a CodePen that shows exactly that.
