Custom section's "Add another link" should be visible at all times

UX

When there’s a lot of items in a custom section, the button to add a new link is hidden:

the add new link should be visible at all times 1
the add new link should be visible at all times 1598×520 18.5 KB

Since this is a necessary button, I think it should be visible at all times to avoid scrolling. Maybe on the left of the Save button?
