When you right-click on an svn revision in the repository browser and do Integrate with branch the commit message is pre-populated with:
"Merged from trunk" <NEWLINE> <revision commit message> " [from revision " <revision id> "]"
Merged from trunk
HPQC462: fixed the defect as requested [from revision 232]
Is it possible to change this template?
The only options I can see in the settings are Live Templates and File Templates.
