Greyhound rule to detect race grade?

[Gonzothegreat]

Is there a rule I could use please to detect the race grade, as in A1 A2 A3 OR etc..?
Instead of having multiple bots, I'm trying to have one that can cover many conditions.

There is no condition to look at the race grade but i suspect some volume conds can help achieve what your looking for

Can it be done with excel linked to guardian?. I mean cell B1 will contain something like "Sund 7th Sep - 11:19 A1 450m"
Search the cell looking for A1 which will return a value TRUE or FALSE and then act on that.Can you basically mimic the find the gap automation bot or a variation of it in excel and so only filter it to fire on certain races ?
