Customizing where @page_title is taken from

I have my page title stored under a page map in the assigns instead of page_title. Of course the problem is that liveview only watches page_title for live updates. Is there a way for me to get it to watch assigns.page.title instead, so that I can give the title live updates?

# Assigns map
%{
  page: %{
    title: "Page Title"
  }
}
