Variables in Zoho Mail Signatures defined by Administrator

Variables in Zoho Mail Signatures defined by Administrator

Good afternoon,

I'm looking at the Admin component of Zoho Mail, and I see we have the capability to define signatures for end users.  We also have the ability to associate with multiple email addresses.

Are we able to use any variables such as [FirstName} [LastName] [Designation] [Department] etc so we can use a single template for multiple users?  If so, how do you define variables in the template?
