Easy Blogging or admin bar with theme choices?

Hi, I want to give easy blogging control panel the ability to pick a theme and the theme they picked options. I need to set this up on easy blogging or branding admin bar. Preferable the admin bar.

It seems that each different themes have different links to the theme options (setting) are different per theme. So it hard to set one line to go to all theme options.

Is there a default theme options link I can use that will go to any themes options, setting, choices, etc..

Thanks
