Custom admin page list sort

[Beetrootman]

Hello,

I am working on a website for a theatre with a calendar of performances. I have a page (all events) which can have children (single event). The children have a repeater field called dates, where numerous dates and other information (number of seats etc) for that event can be set. One event may have three or four different dates.

In the admin page list, I want to sort the children of the events page by the date of the first repeater. Setting the children sort order on the template of the events page to the dates field does not work, probably because the repeater has more fields other than just the date.

Is there a hook I can use to sort the page list? Can I use ProcessPageList::execute? I would need to specifically target that one particular page and its children.

In the screenshots below you can see the page list I want to sort (under Spectacles), and the dates repeater for each of those events.

I hope my explanation is clear,
Thanks for any help.
