Compare Number of bets to a stored value

[noseve]

Within a Guardian rule, I'd like to be able to compare the number of matched/unmatched bets to the number of selections, but there doesn't seem to be any way to do so. Ideally I'd like to run a straight 'If numberOfMatchedBets < (NumberOfSelections-3) then ...' , but would be just as happy to be able to capture the number of matched bets to a stored value.
There doesn't seem to be any way to capture the value - neither can I find a common area where I have access to both the stats simultaneously.
Is it a conscious decision to display different lists of data depending upon in which tab one happens to be in the rules setup screens? What chance of you adding the ability to compare these two figures?
Alternatively, if there's already a way to achieve this, please could you let me know? Many thanks.
