You could try to use our extends feature. “This parameter allows you to build upon the content and settings from another Explore, using the other Explore as a starting point.”
If you have Explore A and Explore B, you could extend A into B or create a new Explore C, where you extend both A and B. You would just want to make sure the views are accessible based on joining the tables together in the new explore. Generally, the extended explore must be joined to the view that the base explore is based on.
