Multi index search into one single hits container

Hi,

Is it possible to show multi-index results together in a single hits container?
The documentation says:

This doesn’t necessarily mean that the results from Algolia indices are combined since their contents could be quite different. https://www.algolia.com/doc/guides/building-search-ui/ui-and-ux-patterns/multi-index-search/js/

But that is exactly what I want. Now every index is shown in a separate hits container.

Thank you in advance
