Button functionality

Hi all

I am trying to create email templates that contain two buttons- "repeat" and "alterations required" for clients to quickly respond to my emails.

The functionality should work as a "Reply" button but also change subject line accordingly.

I attempted to do this through the use of hyperlinks (E-mail Address option), however, that creates a new email chain instead of replying to the current one.

Is this possible within Outlook?

Thanks for your help.
