Possible to use a rule as a fact in another rule?

We're working on better decomposing our facts and rules, and have found that (due to our data model hierarchy), we're having to re-stipulate the same facts in multiple rules. Is it possible to use a rule as a fact in another rule so we can avoid having to copy/paste fact statements into multiple rules which is tedious and error prone?

For example, if Rule 1 states that _FieldA must be true_, and Rule 2 states that _Field A must be true and Field B must be false_, is it possible to construct Rule 2 such that _Rule 1 must be true and Field B must be false_?

該 issue 沒有指定檔案、測試或進入點。先找出規則和事實的評估路徑，接著釐清應如何評估被引用為事實的規則；完成的標準是 Rule 2 可以重複使用 Rule 1 而不重複 Field A，且現有行為仍受到涵蓋。
