Final answer:
Custom settings for grouping are usually not saved in many software applications, contrary to sorting and filtering where custom settings can often be saved. It depends on the specific application, with programs like Microsoft Excel being able to save filters and sorts.
Step-by-step explanation:
You cannot save custom settings that you have specified for grouping. While many software applications allow users to save custom settings for sorting and filtering, grouping arrangements are typically session-specific and may not always be saved across sessions or after closing the application. However, this can vary depending on the specific application or software being used. For example, Microsoft Excel allows users to save custom filter settings within a workbook, and similarly custom sort orders can also be saved. It is always advisable to check the capabilities of the specific software you are using to understand what custom settings can be saved.
