Hi @movingsale
You should be able to do it by using the post object field. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/post-object/.
But, a better solution would be creating custom post types for both news and events, and then query them on each template. To add the custom post type, you can use https://wordpress.org/plugins/custom-post-type-ui/. To learn how to query custom post types, please check this page: https://codex.wordpress.org/Post_Types#Querying_by_Post_Type.
I hope this helps 🙂
