edit header account icon hyperlinks

GST17013

Two questions, relating to the very similar, if not the same topic.

Attached are two screen shots.

1) Shows a dropdown from the account icon dropdown, and I wish to edit the hyperlink associated with "create account" so that I can direct users to the page of my choice.

2) After selecting the "my account" action header button, it shows a hyperlink that directs users to the sites Privacy Policy. I wish to change this hyperlink to a page of my choice.

How do I change the hyperlink in both of these situations?

I've seen a lot of documentation for these areas of the website, unfortunately, I haven't been able to find the answer for these specific issues.

Thanks for your anticipated help!
