Set Reason for closed Event Frames when it is PI Point Data Reference through PI Vision

Currently, when the Reason of an Event Frame is set as PI Point Data Reference, its value cannot be changed through PI Vision Event Table. Moreover, if you try to change the Reason of a closed Event Frame and currently another Event Frame is open, the Reason would be set for that second Event Frame, because it is always written at the current timestamp ('*'). Sometimes it's necessary to set the Reason as PI Point because you want to make later calculations with it. So, it is necessary to be able to set the Reason with the Event Frame End Timestamp (for example) instead of the current time, making possible to set Reasons for closed Event Frames.
