If I understand the ask correctly, yes, completely doable! You’’ll just need to tinker a bit in the record detail pages menu.

On the List page that you’ve duplicated into the second interface (Interface B, we’ll say): you’ll want to navigate to the Page > List menu. At the bottom you’ll see the “Click into record details” toggle. With the toggle turned on, click on the gear to see this little pop-menu:

Clicking into the dropdown shows all existing Record Detail layouts. You’ll want to make sure the one you want to replicate and then modify has a checkmark next to it. Once that’s done, just click the Duplicate current layout option:

Once you’ve duplicated it, it should automatically open your new, fully distinct record detail page, like so: 

I recommend renaming the Page name to something specific (e.g. the original interface’s record detail page name, “with Button”, or “Record Detail - Interface B Version”), just so it’s easier to keep track of the different versions and options as you potentially build more ways to interact with your data. 

After renaming and making whatever changes you’re hoping to make, you’ll just Publish as usual, and you should be able to see that each List interface now has different Record Detail page layouts.

Hopefully that addresses your need here.

Yes, I agree with ​@stagandforge and the very neat explanation given!

Just to add more context, when you duplicated the List view, it created a copy that points to the same complex record detail you created. So what you need to do is create a separate copy of that complex record detail and have your duplicated List view point to that separate record detail. Which is exactly what the stagandforge’s explanation does.

Hey ​@dbidinost,

Yes this is possible, and you should be able to achieve that following instructions above. 

Having said that, if you need some extra help feel free to grab a slot and we can spend 5 minutes together going through it.  Happy to help!
