I hope K2 Items URL like this:
www.domain.com/201210197
www.domain.com/201210198
www.domain.com/201210199
......
www.domain.com/(Unique ID)

In K2 control panel at "Parameters" under "Advanced" tab, I set Unique ID option is true, and URL display like this:
www.domain.com/201210197/sometext
www.domain.com/201210198/sometext
......
www.domain.com/(Unique ID)/(item alias)

I do not want the Item URL contains title alias, because my language is Chinese, the site uses characters in non-Latin characters, the URL contains alias will cause a lot of trouble, and only use the Unique ID as the URL of the Item is very friendly.

If there is no such setting options, whether to modify some files can implement this feature?

I tried consulting sh404SEF support forum, but their response is:
"For a such thing you should ask on K2 support forum, as they are the one who built and maintain their own sh404sef plugin"

So I try to come here to consult, hoping to get help, and also hope that help users to encounter the same problem.

Thank you very much
