Display sections in done and all view of apple reminders

Hello,

I try to use the grocery feature in reminders, but it falls short when creating a shopping list. You can do a Checklist with sections (which I user for the different shops) - which is very helpful - but in then in Done/All views (which then is use as a shopping list) all the items are not displayed in sections, just a primitive list. Is there a possibility to display sections in the Done/All views ? (Sorry the screenshots are in German)

If not, how can I get in touch with developers to suggest that ?
