Signature modification on reply

Hi all,

I know this has been up before but to no solution in later RT-versions. Running 4.4 over here and tried a heck of a lot regarding this:

Basically this is not applicable in RT 4.4, or at least I can’t manage to get it to work. We are trying to implement RT as a ticket system for the organization and this is potentially a show stopper down the line, basically all modern communications we do are latest reply on top, hence the need for the Signature to also follow above quoted replies.

Anyone that can give a pointer on how to get this to work?

Regards, Joel
