Auto unblock randsomware in Sophos Cemtral

Is it possible to change this default behaviour ?

On https://support.sophos.com/support/s/article/KB-000036287?language=en_US is

Note: The computer will automatically be unblocked after 8 hours if the Sophos Central Administrator takes no action to prevent a potentially valid application from being blocked indefinitely. If the remote attack re-occurs, it will be blocked again.

Thanks
