How do I update a website custom property in Sharepoint?

I have some code which does the following:

const string KEY_CHK = "Microsoft.IW.PartCheck";
SPWeb curWeb = SPContext.Current.Web;
if (!curWeb.Properties.ContainsKey(KEY_CHK))
{ 
   curWeb.Properties.Add(KEY_CHK, "true");
   curWeb.Properties.Update();
}

This runs as a webpart in a master page in Sharepoint 2007.

I would like to be able to update the value of a property in a non-code way.
Through Sharepoint admin screens, or via Sharepoint designer.

Is this possible? Where/how can I do it?

From stackoverflow

• nope, you cannot set web properties via the UI. maybe there's something on CodePlex

• Hello,

  Try using SharePoint Manager 2007 from http://www.codeplex.com/spm.
