Add a new custom field (a reasonable name would be 'Bug Description'), that contains the template you want to use as the default value (see for details). Here's what you have to do (no doubt getting it to work is cumbersome to - but once it works - it works perfectly and flawlessly): Note that this is from memory, so there might be small mistakes here and there - but the gist of it is correct. Since it's anything but obvious, even once you have the idea - I'm sharing this, both to help others and also - documenting it so that if I have to do it again in the future I won't have to spend as much time tinkering with the system. Still, getting it to work took some time. For the record - I didn't come up with it myself - I was given the tip from a new employee that did it in a previous company. It's just not very intuitive to come up with - and that's an understatement.
So, turns out there IS a way to do it without adding any extra steps or changing the (human) workflow in any way.
