Photoshop :: How To Save Brushes Texture Property With Brush

I just realized that brush presets won't save a brushes texture which is slightly annoying. I'm in CS6 btw and I'm familiar with photoshop which is why I'm posting here.
 
For example I have two brushes, a watercolor one (with texture turned on in the brushes panel to the watercolor background texture) I save it as a tool preset (I'm not making the saving as a brush preset mistake). I go make a paintbrush brush with a different background texture and save it as a tool preset. When I go use the watercolor brush it has the paintbrush background texture and NOT the watercolor.
 
I never touched the texture property until lately so I'm not sure if this has always been this way...
 
Is there some way to save that property or do I manually have to go and change it each time. I want to be able to share my brushes. Do I have to instruct people on which texture to use?
