-Yes. To consolidate the views in the Schema tab, Segment automatically converts `page` calls into `Page Viewed` events that appear in the Schema Events view. Segment recommends adding a `Page Viewed` event to your Tracking Plan with any properties you want to validate against. At this time, you cannot validate that a specific named page (`analytics.page('Homepage')`) has a specific set of required properties.
+To consolidate the views in the Schema tab, Segment automatically converts `page` and `screen` calls into `Page Viewed` and `Screen Viewed` events that appear in the Schema Events view. Segment recommends adding a `Page Viewed` or `Screen Viewed` event to your Tracking Plan with any properties you want to validate against. At this time, to validate that a specific named page/screen (`analytics.page('Homepage') | analytics.screen('Home')`) has a specific set of required properties, you will need to use the [JSON Schema](/docs/protocols/tracking-plan/create/#edit-underlying-json-schema).
