I have been using the heat treating method for AEB-L with a 1,725°F pre-quench explained by

in this thread. With my small oven treating six or eight blades makes for a very long day with the two quenches, subzero treatment and tempering. In this thread from 2018, there was a discussion about pre-quenching one day and finishing the heat treat the next day. @Larrin recommended a snap temper following the pre-quench. I have tried this before and had no problems.
Now, I am wondering how long one could wait after the pre-quench before completing the heat treat. Is there a shelf life for pre-quenched blades or do they keep pretty much forever? Obviously, I do not plan to keep them around forever, but it would be nice if I could pre-quench a bunch of blades one weekend and then finish the heat treat a week or two later, or maybe even a month. Also, I am wondering if there is a recommended time/temperature for the snap temper.
