Hi – great question.
It’s important to realize though that we can only offer limited support for customization requests like this one (though we’re happy to kick around some ideas and hopefully get you pointed in the right direction).
please email me at [your email address] when this is answered. Thanks!
Please also note that we don’t typically deliver support via email. This forum is the correct venue for requesting support and we’ll post our updates here. What I’d recommend if you haven’t already done so is subscribing to receive updates via email 🙂
To the issue at hand, are you literally using display and have you tried eventDisplay instead? What priority is your own pre_get_posts action running on? It’s worth remembering our own runs at priority 50.
