Variable Controls for Standard Texts?

Content

I'm wondering if there is the capability of creating variables that must be addressed before a representative can send that chat script to the customer? As an example, our staff needs to create a case and provide that case number and we'd like to do that in part of our closing. A simplified example would be the rep choosing this Standard Text;

Thanks for contacting us today. For reference, your case number is {{{CASE}}}.

I'd like to ensure that the representative addresses the {{{CASE}}} section and doesn't send that directly to the customer creating an embarrassing situation.
