Multiple objects to be displayed in a metric card

Is it possible to include multiple objects that should be displayed in a metric card?
Currently I use metric card with object property, but it says->Object set (with a single object)
And it displays if it has 0 or multiple values

What do you want to display?

For example: Let’s say I had a flight and I wanted to display some metadata such as a count of checked in passengers.

  1. I would create an object set variable of passenger OT filtered to those checked-in.
  2. I would create a new numeric variable that is an object set aggregation of my passenger object set.
  3. You can then render that numeric variable in your metrics card.

Hope this helps!
