Thank you!

It cannot yet do that. But is not difficult to achieve...

You need to implement a new index type "RangeListIndex" which
relates to "RangeIndex" in the same way as "KeywordIndex" to
"FieldIndex".

When you are ready to forget about the "aggregate" combiner,
then you can directly carry over the implementation of
"KeywordIndex" to your new "RangeListIndex".
The new index would probably inherit from "RangeIndex" in order
to use its "storage" methods.
