Xarchiver with SU level access

[Android3000]

Hi,

 

Do I have to create a Default Custom Command line under Preferences/Advanced in Xarchiver to allow zip files to be extracted with SU level access or is there a way within the desktop GUI to launch Xarchiver with SU level access?   I want to extract a .NET binary archive to /user/local/bin, which needs SU write access.  I realise I could use the command line for this but I like working with the desktop GUI.

 

Thanks
