Thanks a lot for the response. Indeed Retrostats is definitely almost (if not all - only had a very quick look) giving everything I want.
Not sure why, I didn't get any email notification so just found out about your answer today (as I have another question).
So thank you again and I'll switch over to retrostats for now :-)
