Custom my-account login page

Hi dear team, just to ask you..

Is there a possibility to create a customer log in page separately, and when a guest or logged out person clicks on login/register (my account) on the menu bar they get redirected to the sign in page I’ve created?

Or maybe a better option, to hide a myaccount page when the user is logged out, and to be shown in the menu when users are logged in?

Thanks 🙂
