重力形式:分组有条件确认

I know in Gravity Forms you can have condition-based confirmations, however is there a plugin or even programmatically where it's possible for the conditions to be grouped?

Eg. rather than having

1a AND 2b AND 3e

or

1a OR 2b OR 3e

Can we have

1a AND (2a or 2b) AND (3b or 3c or 3e)?
