I wish to delete some unused multilevel lists (not styles). In the screenshot below,, this would be "Lists in the Current Documents". This is not the same as a list style, which relates to: https://shaunakelly.com/word/numbering/numbering20072010.html, and is what seems to the usual reply I find online when searching how to delete multilevel lists.
I have lots of mulitlevel lists in my document (potentially >1000), which I wish to remove and replace with the one list style shown in the screenshot. Said list style is similar to one of the default numbering lists, but with the symbols slightly changed. The number of lists is bad to the point that the Word document will freeze indefinitely if a new list (multilevel list or list style) is used. This is an issue for one specific Word document used, though it occurs on both a Microsoft and Mac computer.
