ACF allows you to set the title of each layout using this filter https://www.advancedcustomfields.com/resources/acf-fields-flexible_content-layout_title/
Using this filter you can use a field in the layout, for example a special “layout name” field to allow the editor to supply the value to be shown. This can improve usability for the editor in identifying the layout when collapsed to make it easier to find the one to be reordered or edited.
