I am now despondant - I have only just realised what the date of the last post is.
My zest and relief at apparently finding what I was looking for led me to rush in and post.
Now I realise I am a fool - and I guess it was not meant to be.
But on the slim chance that this mod exists and someone knows where to find it, please post a reply or e-mail me and put me out of my misery.
Thankyou in advance and I will leave you now to search on until dawn...
