It is not possible to set a timeout limit on one's own account beyond 120 minutes. It would be very helpful, particularly for Admin accounts, to enable a longer timeout as it can cause significant interruption to work on reports and subsequently inconsistent data extraction if the exact parameters are not repeated. A revised limit of 4 or 5 hours would not present any greater risk of data breaches, if that is the purpose of the timeout, and would enable complex tasks to be carried out without interruption.
