Transport Rule disclaimer append to both message and Calendar entry

Hi,

I've created a transport rule to add a disclaimer text to an appointment that has a specific user as recipient (ex : send to "jp@gmail.com")

My problem is, I want the disclaimer text to be added in both the invite request and the calendar entry. For now all I have managed to do is adding it to the request and to the calendar entry of the receiver ... but I don't find any way of adding it to sender calender entry ...

Is there a way to do this ?

Thanks
