CAladdin,
There are two options. The first is to redesign your spreadsheet as a daily tracker. This usually involves creating a row for every day, where your Running Total would reference your previous day's 'Today' and 'Prior ttl' to create your new 'Prior ttl'. Here's an example.

With this sort of model you'e need to decide how you wanted to split up your 'Pairs'. You could use multiple tables on a worksheet, or you could simply create a worksheet for each pair. The advantage to this is the daily tracking capability.
Alternatively if you want to maintain your above format, you will need to consider a code solution. I'm not sure that wouldn't be almost as much work as manually transferring data. I would do it, but then I'd rather write code than manually transfer data any day of the week. I've spent an hour to automate a manual task that takes 5 minutes once every month. A year just to break even on the time.
I hope that at least gives you an idea as to direction.
