News Filtering in News Site in Sharepoint

Hi all,

i have a news site (communications site) in SharePoint online. There i have created a filter to show the news that are 2 weeks old. I created a column with name expirations date and the filter checks this date with the date of today. On the main intranet site we have a web part that includes the news-flow of 3 news sites. The news are not shown filtered. Unfortunately i cant create the same filter because the news pages in site-contents are existing only to the initial news site. Is there any way to show filtered news to other sites? Is it possible to filter news from another site based on date? For example from the date of creation and for 2 weeks more as i mentioned above.

Thank you for your time.
