How can I clean a Chrome profile in a custom location?

I start Chrome with the command "chrome.exe --user-data-dir=e:\data\Chrome\" rather than having it in my %appdata% folder.

Is there a way of making CCleaner clean up the same files it would in a standard Chrome User Data folder without having to manually look up and add every file?

You can't. The Winapp entries for Chrome all use SpecialKey and not simply normal paths to files, so I'm afraid the path is hardcoded into CCleaner.sad.gif
