FontBook Add fonts to a collection

Is it possible to add the contents of a specific folder with fonts into a collection?
The fonts are in the root the level of the computer:
Macintosh HD/Fonts_1/Basic set

So far I’m able to create a new collection but how do you add the fonts from the root level into the new collection?

tell application "Font Book"
	make new font collection with properties {name:" start set"}
	set validate fonts before installing to true
	set enabled to true
end tell

Once the new collection is created a Computer library will be automatically created in FontBook is it possible to disable it?

I was trying to use Automator for this but there is no option to add a Collection
