I am using smarttemplate4 with Thuderbird.

It is possible to automatically add a fixed string to the beginning
of each message using smarttemplate4.
I created a reply template which works well, but I have not found
a way to add my own string to the beginning of the subject.
For example if the original subject line was "How to fix gizmo"
I want the reply to look like this "Support answer - How to fix gizmo".

I'd like it to be something like this:

%subject%:=Support answer %subject%

Is it possible to do?

Thanks a lot,
