Its functionality I knew I couldn't be the first to be looking for, so when I couldn't find it I assumed I had missed something and went playing as well as asking!
In my case it was my lack of understanding that the sitewide feedbacks that you can add to the front page could in fact be reported on at a course level with the filters, not just as a single whole site feedback form. Every time I've used them previously it has been on a single course instance rather than the concept of a shared one across the site. It was talking my way through setting up a trial one and stepping through that which helped me find the solution - woods and trees come to mind lol!!!
But yes, rubber-ducking is a very useful tool in my armoury!!! Although there are times when I think it might be more useful if I could get the rubber duck to explain certain things to me :D
The original requirement has come from our university merger and looking for an existing built in functionality in Moodle to replicate the external links that the other part of the university use between their Blackboard and QuestionMarkPerception forms for this purpose. I may still have to create the links to the external tools, but I wanted (for my own benefit as well as the student/teacher experience) to know how it could be done, simply (rather than my laborious workarounds that would have taken a couple of days of time!) and within Moodle without the need for external tools.
