Is it possible to add attributes from one entity to another?

I want to add the attribute distance from sensor.em_travel_time to the person.emma entity. Is this possible? if so, how do I do this please?

I tired using
Distance: {{ state_attr('sensor.em_travel_time','distance') }} in the markdown card but soon realised this wasn’t what I was trying to achieve.

Add to. No. Present the information in another way. Absolutely.

So instead of specifying a how (which won’t work) Whats your desired end result?
