Turn off reply to customer in tickets?

Hi,

we are on the free version of ZOHO Desk, and are thinking about upgrading to the full version soon. We pay for licences to ZOHO CRM, and understand that we can attach tickets to our CRM clients within the full version of Desk.

However, I would like to know if there is a way to remove the ability to forward or reply within the ticket? We plan on using the ticketing system internally, and do not want to use any of the public / client interaction functions. Basically, I do not want my staff accidentally clicking on the Reply or Forward option within a ticket and accidentally sending something to our customers.

for example, in the test ticket below, if we click one of these items, we will be emailing information to our clients, which we do not want to do.

Removing the contact details from the client is not an option, as we want to be able to sync the ticket items with the CRM record, and the CRM record contains the contact details.

thanks.
