Edit URL Link On one Page

I would love assistance on what should be the simplest thing ever, but as my new trial and experience with SS is proving, SS has gone out of its way to make this difficult and inaccessible.

For the template I selected, I would be very happy it keeping it as my landing page, however the only problem is that as a gallery, it wants to connect directly to the sub-breadcrumbed albums (or only) blank page therein.

Is there a way to just change the URL link for that ONE link so it instead routes to a page on my main navigation?

I spent a while with the live chat and they said it was not a possibility.

Like I said, I am new to SS, but this is such an asininely easy thing to just toggle on/off WYSIWYG for that individual page. Am I missing it?

Would really not have to start from scratch and find a new site hoster,
