Hey ​@Judy12,

Unfortunately there is no way to duplicate an interface from one base into a different base! Duplicate page will only work for duplicating the page within the same base (and choosing within which Interface to create it).

If helpful, you are looking at a Timeline page layout in case you want to create that from scratch on your own base.

Feel fee to reach out if you need any help setting this up!
