Well actually you can't but that does not always mean you can. First of all you would need Excel VBA Macro and QC COM API knowledge. Then you would need to contact HP support to give you the password for there excel Add-in (which they say they do but only in case you have some issues which they are not able to solved). Then you need add code to the same to insert the call to a template.
Now if i were you then looking at the above suggestion i would take a decision based on the importance and the amount of usage of the need to do it. And if i think that it would save more hours then i spend on it, then i won't look back.
