How to add a customized/dynamic Zoho Booking link in email footer?

We just installed the latest version of the Zoho Desk <=> Zoho Booking extension from the marketplace and are quite happy to see the feature where a ticket-specific appointment booking link can be inserted in a reply.

Is there any way to configure this such that the email footer ALWAYS contains this link? We want to give our customers the option to jump on a Zoho Booking appointment SPECIFIC TO THE TICKET anytime during the email conversation without needing the agent to explicitly offer a ticket-specific booking link.

Is there a feature in the extension itself? Alternatively, does Zoho Desk support mail merge tags in the signature which can be used to construct the dynamic booking link internally used by the extension, something like:
