Well, that's exactly what I did Thanks anyway!
However, still surprising that Fabrik does not have a builtin function for that - seems to be a very fundamental function for people who do not want to build a package...
It's the first time I recall ever being asked for this. Typically if something is a fundamental function, we get asked for it a little more often than once a decade.
Also if it's something easily do-able through another extension specifically designed for doing it, there's little point in us reinventing the wheel, creating more code for us to maintain.
