Command Line syntax question

[BRowe_23]

How do I combine commands on the #XSOAR command line?

If one command wants a list, I would like to call a list, not enumerate it on the command line.

For example, the RandomElementFromList works like this:

!RandomElementFromList count=1 value="banana, orange, potato" may randomly respond with "orange".  Easy Peazy.

getList works like this:
!getList listName=fruitAndVegatables will respond with the entire list.  Nice.

What if I have a long list named fruitAndVegatables stored and I want a compound command that will pick a value by combining the randomElementFromList command and the getList command? What is the syntax?

My guess is this, but it doesn't work:

!RandomElementFromList count=1 value=!getList listName=fruitAndVegatables

What combination of quotes, curly brackets and delimiters do I need? I am interested in the syntax.  I did not see a relevant example.

Thanks
