Specifying custom favicon w/o assets directory

I would like to customize the favicon of my dash app directly with a link to the favicon. Including the favicon inside an assets folder works, but I have to incorporate a separate assets folder for each app.

I saw that there have been numerous threads on this, but I am not sure if there is a solution for my problem in the current version already.

Currently I am passing a list of scripts and stylesheets to the app as so:

app = dash.Dash(name=__name__, sharing=True, server=server,

This is very convenient and flexible for css and js files.

Would it be possible to add external_favicon="http://some_host/myfavicon.ico" to the keywords?
