Thank you very much Ross I was looking to fix this issue as well.
I wanted to have a “View More” link at the bottom of the event tooltip in grid view that would link to the same event in a list view on another page of my site. I was able to do exactly what I wanted with the Event Display Builder! Below is some example code in case anyone wants to do the same.
In the Event Display Builder for grid view:
<!-- other event info here -->
<p class="gce-tooltip-link"><a href="/events/#[event-id]">View More ?</a></p>
In the Event Display Builder for list view:
<div id="[event-id]">
<p class="gce-list-event">[event-title]</p>
<!-- other event info here -->
</div>
