Legacy templates allowed you to use a different template for any specific instance (Widget or shortcode) for a list view. PHP templates have only one option available.
Describe the solution you'd like
Most likely, this would use an ID attribute or similar attribute on the shortcode/widget that could target a specific variant of the template. E.g., instead of upcoming.php, you'd have upcoming-widget-1.php.
