 Is it possible to move the Trigger (T) cursor under the transitional storage mode?

No! Under the transitional storage mode, the idle frame is recorded as state/duration (1 or 0 / time), not in data format, so the software is not able to determine the ratio of the memories on both side of the trigger cursor. Hence, it is not possible to move the trigger cursor.
