@swinggraphics can you give more detail about what you mean specifically?
For example, start and end times of events and ticket prices?
Regardless of my specific case, us three a filter for the output? Maybe it’s not meta data but adding classes, a wrapper, or reordering elements in the output.
If you need to display something custom on the front end where the grid displays, you can use the_excerpt filter. The block runs that core WP filter when displaying the excerpt.
If that doesn’t work for you, let me know. We can consider adding custom hooks and filters in a future update.
