Is there a way to slow hide or fade out entities in monster-card using `show_empty: false`?

I’m using monster-card to show the lights that are on, and to show which motion detectors are triggered (and subsequently hide them when they are off). What I’d like to do, is when a light is turned off or motion is un-triggered, the entity would fade away instead of immediately disappear.

For example - flipping off a light on the lovelace panel but realizing I hit the wrong one (can’t undo it because it’s already off the card). My motion detector just stopped - but which one was just active? Can’t tell.

Any ideas?

I believe that if you switch to auto-entities you should be able to make a filter which shows lights that are on and lights that are off byt have been turned off within a certain time. Maybe.
