Combine 'numericMenu' and 'sortBy'

Hi, we are using Algolia InstanSearch for an overview of our events. We have a filter ‘upcoming events’ and ‘past events’. The filter is working with a numericMenu:

items: [
     { label: 'Upcoming events', start: today },
     { label: 'Past events', end: today },

But we want to re-order the past events so that the order there is reversed from the upcoming events. Is this possible?
