Document with associated date ranges (multiple dates) for events

Hi,
Is it possible to assign multiple dates to an individual document?

For example an event that spans multiple days starting on 1 January 2021 and ending of 4 January 2021.
Would have four dates
1 Jan 2021
2 Jan 2021
3 Jan 2021
4 Jan 2021

And using a date parameter in the search would then look to match any of these four dates against the search parameter range.

Looking at the documentation Metadata class types - Funnelback Documentation - Version 15.24.0 it makes me think that only a single date can be used.

Or can it simply be done by matching the d class against a group of dates in an XML feed. And Funnelback then handles the ranges itself?

2021-01-01 2021-01-02 2021-01-03 2021-01-04

where d class is assigned to dates/date

In this old forum post it describes what I want to do but I need to be able to filter by facet and by date so this wouldnt work as far as I can tell.

Using the Event search detailed here Event Search - Funnelback Documentation - Version 15.10.0 wouldnt be sufficient for my needs as I also want to filter by other facets such as category and audience type.

Many thanks,
David
