Question request, add custom to "on this day"

Because I have a lot of persons in my tree, the "On This Day" section is way to big.

I did a (dirty) customization of webtrees/resources/views/lists/anniversaries-list.phtml
by adding a hard-coded filer, to see only my direct family:
 <?php if(strpos($record->fullName(), "Breetvelt") !== false ||
                  strpos($record->fullName(), "Breetveld") !== false ||
                  strpos($record->fullName(), "Breedvelt") !== false ||
                  strpos($record->fullName(), "Breedveld") !== false) { ?>

It would be much nicer if this can be added somewhere in the configuration to define a couple of names to filter it.
