ConditionsPlayed Separated by block

Hello,
Is there a TrialRecord variable or built-in way to separate TrialErrors and ConditionsPlayed by blocks? These arrays store the conditions and trial outcomes across multiple blocks throughout the session, I would like to access these variables for the current block only.
If there is no built-in option, I will just count the indices of TrialErrors and ConditionsPlayed backwards from CurrentTrialWithinBlock.

Thanks!
