Photoshop :: Extra Selections Within The Marquee

I'm current working on some anime mangas (basically comic books for those who don't know) for cleaning as well as de-bubbling. I was able to create a action script to easily remove all the characters within the text bubbles but I'm trying to come by a more efficient way. My current method is nearly flawless when it comes to round or square text bubbles/boxes as well as some slightly complex ones. But when I come across extremely complex bubbles my method cuts corners and remove areas I'm not intending too...so my question is this..

Let's say I use the magic wand tool to select inside the a text bubble I'm trying to clear...So currently it has the white background of the inner bubble selected as it surrounds the text I'm trying to remove. Is there any quick command or shortcut that can select everything within that area?...Atm I have a action script set up to expand by 8 pixels and then contract by 11. This way it can expand to select the characters I'm trying to remove, and the contraction will bring it right back within the vicinity of the bubble. It's then followed by a paste pattern which I've set up to match the feel of the page. But yea...trying to figure out if theres a way to just select the insides in a different way...a method that doesn't expand and contract...yet has similar results. I was trying to look around for a function in photoshop to just select area's within the marquee's inner untouched areas.
