I appreciate your question and the desire to customize it for your use. However, we cannot provide such in-depth customization help, per our Terms.
Additionally, I didn’t find that as an existing feature request at our plugins’ UserVoice page.
Please do add your feature request there.
This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
Once you post it, feel free to link to it from here in case anyone comes across this forum thread in the future.
P.S. If you are looking to do it yourself or hire a developer, you may find some help looking in this file:
/wp-content/plugins/the-events-calendar/src/resources/js/tribe-events.js
And searching for “tribe_ev.fn.tooltips” (line 842). It mentions that it, “…covers all tooltip hover events for the various views.”
Thank you very much for your understanding. You are a valued customer.
