[Feature] Is there a way to make other graphic elements into blur state when highlight multiple series ?

### What problem does this feature solve?

When I highlight some graphic elements in multiple series or select one graphic element, I want to mute other graphic elements in order to visually distinguish between selected and unselected graphic elements.
I tried using dispatchAction({ type: 'highlight' }), but the options (emphasis.focus = 'none'/'self'/'series') can not mute the others in multiple series. And I tried using dispatchAction({ type: 'select' }), no options to mute the others.

### What does the proposed API look like?

Add dispatchAction({ type: 'blur' }) to mute graphic elements.
