Link an Url to a Defect : how to alias the Url via OTA ?

Hi,

Here is my code to link a Url to a Defect :

Set oAttachmentFactory = Bug.Attachments
Set Attachment = oAttachmentFactory.AddItem(Null)
Attachment.FileName = MyUrl
Attachment.Description = "blablabla"
Attachment.Type = 2
Attachment.Post

It works fine but, the visible name of the url is the page and its parameters of the url (?foo1=test1&foo2=test2...).

Is there a way to replace this ugly thing by an alias ?

I have not found how to set the name value (according the OTA Reference book, it is in read-only mode).

Thanks,

Regards,

Sebastien
