I posted a similar question a day or so ago, and didn’t get a response. In further searching (my first one was too specific) I found someone suggesting a redirect plug-in to accomplish it. Looks like you just create a page that is a redirect to whatever URL you want, with other controls.
‘Quick Page/Post Redirect Plugin’ was its name. Haven’t had time to play with it yet.
Next, to make the button an image of its own….
