I have a 1 BBL fermentor that actually has a 40 gallon capacity so I am able to double batch and get 36 gallons. It makes for a long brew day but worth it to me and I enjoy it, so spending 8+ hours in the basement is great!

With that said, I want to brew another double batch but have time constraints. Is it advisable to brew one batch, pitch the yeast and let it start fermentation AND then brew the 2nd batch 1 week later and add to the already fermenting wort?

Not only is it OK, it's preferable and often done in commercial brewing. It's how Denny Kong was made.

That's good to know! I did not realize commercial breweries do this. I assume it would save them money on yeast.

It's actually much more practical. Most breweries have fermenters that are far larger than their brewing systems. It takes 2 or sometimes 3 brews to fill them.
