Yes, that is how my mini system is set up. Drip Works also provided a main filter and basically on off switches for each bed. But it is set up as you describe yours. Sounds like you a nice set up. And such a large garden. I envy that. My entire drip system is only for my three raised beds. The only other vegies are in large pots (about 24 inches in diameter) sunk in the ground in my flower gardens. I have a huge amount of slugs and other such creatures to contend with. I should have wrapped the copper wire I have around the pots first thing. Now that the slugs are in the pots they will lay eggs. I need to get them protected with the copper and figure out how to kill the slug eggs before next spring.
Suggestions anyone? Come on Rick. You have an answer for everything.
