white label each agent property website

Hi. It would be wonderful if we could customize (white label) each agents property website URL differently so that the "view.spiro.media" or my company’s white label (“view.thompsonrealestatemedia.com”) isn’t showing first. I know that in the property website editor, under website settings, we can change the URL Slug but the "view.spiro.media" or our custom white label for our company still shows first in the URL.

Thanks.
