I'm not sure the answer you're looking for is this but...
If I understand correctly, your solution is quite simple.
Create a folder under "assets" folder which is in the root of your SS installation. And just put your any neccessary HTML files inside this.
Then go to the page edit screen and click on "download a file" under link menu. Select your folder and after your HTML file.
Thats it :)
