Subfolders for html pages

Is there a way to use mos.yml to put files into subfolders in the filesystem? For example, I’d like all webpages stored in a “config” folder so when they are called during the setup process they look like:
http://192.168.0.1/config/page1.html

Right now it just looks like http://192.168.0.1/page1.html

SPIFFS is flat, so the answer is no.
