Can we set Cross module association owner as Both

Hi, I have a requirement that My entity should be associated with the User entity. In our application, we have custom login. so we have created a Login entity and it's associated with a User entity using  1 – * association . Here whenever I try to get Login entity Its always gives a list of login entity, then I need to filter or take an object. But it has only one object within the list. So Why it has this limitation as Cross module association should not have owner as Both. Can we overcome this

Could it be that you want to retrieve only the first option instead of all, it will then return an object.

Options – Range – First is what you are maybe looking for.

Good luck!
