Associate notes with custom stats?

Currently the notetracker is triggered by filters. Can it be extended to be triggered by custom stats?
For example I have a custom stat for 3b non all in %, but it is not possible to make a filter for non all in 3b afaik using the current operators. It is only possible to filter for 3bets with sizes between certain values.
Thanks.
