Mini accessory cases for Think Tank Change up shoulder straps?

My Change Up's shoulder straps look like they could accept some kind of small attachments on the shoulder straps, like for memory cards or batteries, but I can't find anything on their site that looks like it would fit.

Modular Pouch

If you're looking for a smaller solution, I've just bought 2 Joey packs from Black Rapid straps; just the right size for my blackberry. Straps on the back are very convenient. If it were on your belt for instance, you can hang it vertically (covered opening at the top), or horizontally.
Will work well withany shoulder bag with a removable strap.

edit: Mike here's a link for the product I tried to describe...

Hope this helps. They have 2 little Joey pouches. The 2 is larger than the 1...

I Joeys might work. I was hoping for something smaller than the TT modular pouch, more like something the size of a couple of batteries. I wonder if the Joey's split ring at the top can be hooked through one of the TT strap's loops to keep it in place.

Mike, see above. This little pouch will hold at least one rechargable camera battery; probably 6 or so AA's.
I have a Blackberry Bold 9700. It holds that very well.

My doubt is about how well it would stay in place on my TT strap. I don't want something that's going to keep sliding down.

If it were mine, I would get some velcro and fasten one piece to the strap and another to the case...
