Adding to @lpb ‘s advice, you could also consider using a single select custom field instead of sections. This would allow filtering for the custom field values you’d want. And “hide empty groups” (three dot menu under group) allows to show only the tasks with the field values you’ve filtered for.
You can sort the custom field groupings in two ways, both the original list order, or the reverse.
