Meta tags for ticket templates

I've been thinking about something that could be useful for those who use Ticket templates but I don't know if it's possible.

The use of meta tags to be set up on predefined fields.

For example:

Set up a predefined Title to pick up the day of the week, or the month that the ticket is open, or the entity name... but using meta tags. Like those we use in newsletter services like mailchimp or even the same we have in notification templates.
