Most of my listings end their third relist either 1 or 2 days before the end of this month, but a small number won't end until around 5 days into November, and I'd like to have them all start on the first day of the month so that they end on the 30th, at which time I would replace those items which have sold during that period.

Is there anything preventing me from ending all current listings on the 30th of this month, then reinserting all 40 new listings on the first day of November so that they will then all end their 3rd relist at the end of November? I can see nothing in the help files which would prevent me from doing so, but I'd really like to be sure before going ahead.
