Not FR

it is possible to put an entire block of "instructions" into a variable?

Like this:

#yaml editor/lovelace.yaml
#...
variables:
  tap_var: null
#...

#card yaml:
#...
type: custom:button-card
template: example_template
variables:
  tap_var:
    action: navigate
    navigation_path: /hassio/dashboard
#...
