[Greasemonkey] GM_openInTab - tab's label

[Al]

Hi,
Is there anyway to control the new tab's name or label which results
from something like 

GM_openInTab('data:application/xml,'+myXMLString);  ??

currently, this creates an ugly looking tab labeled "data:application/xml ...."

Would be more 'user friendly' if I could label it something to draw 
attention or have some reference to the service that spawned the new tab.

thanks!
Al
