Thanks for the quick reply Jeremy. The problem is that my module does not contain the Versions list, but needs to retrieve data from a module with the Versions list (specifically it needs to retrieve budget data). I can't really work via your suggestion (Version settings module), as it does not allow me to write a LOOKUP or SELECT that will work, it only allows you to write a conditional formula, if you have the Versions list in your module (which I don't have).
Considering this issue and many others I've had because you can't define a line item as 'Version' format, I believe Anaplan should take this up and hopefully creates this functionality for one of their following releases.
Thanks heaps for your efforts and thinking along.
Kind regards,
Albrecht
