Sharepoint subsite with URL

Hi,

   I am successfully creating sharepoint sub-sites using meetings.asmx (createWorkspace) methods.This Method has only four input parameters while subsite creation.

• title
• webTemplate
• lcid
• TimeZoneInf        

So now when the new subsite is getting created with URL as https://<sharepoint-location>/<main-site>/title.(This title is same as what I passed in)

 Now I would like to have a different title then URL(e.g in URL I need just file id and as a title I need file_Name).

I tried modifying meetings.asmx to include URL as an input parameter but it didn't work.

Is there a way to achieve it using meetings.asmx ? or I have to use different web service ?

Thank  you,

Omar
