Save and Continue not available when creating a record from subtab

Summary:

We noticed save and continue is not an available button if you try to create a record through a sub tab. Is this something we can enable?

See screenshot, you have save and continue button if you directly create a record (native or custom object alike) through the create button on an object saved search list

But if you create a record through subtab from another object (go to an opportunity record --> Go to the milestone subtab --> click create) you won't see the save and continue button

How can I enable the Save and Continue button for the INdirect create route?
