Thanks for the very fast response.
I really appreciate your hard work and the time invested in trying to help me.
I have looked at each and every link that you posted but sadly found nothing that fully ticks all boxes.
Here are my findings:

Perhaps I will try this at a later date.Once again, thanks for trying to help me out
Cheers
