Tasker: Use variable in "A Thing" action

Would be great to be able to use a variable for at least the command in the A Thing action. Variables for all fields would be fantastic.
I’d like to have all of my A Thing actions in a single task and pass the Thing variable and the Command variable to the task in the parameters.

Welcome to the community and thanks for posting. If you tap the tag icon in the action bar while editing the ‘A Thing’ action, the fields change to text fields that allow free form entry of command names or the use of Tasker variables.
