Hi Craig,
That would be nice, but it's not possible for now. Check this thread for details:
http://devcentral.f5.com/Default.aspx?tabid=53&forumid=5&tpage=1&view=topic&postid=21564
F5 created a CR noting this feature request. It's CR96170. If you would like to see this functionality added it would help the cause to open a case with support (https://websupport.f5.com) asking for your request to be attached to the CR.
Also, can anyone in Development provide any info on whether this is likely to be added in a future version?
Thanks,
Aaron
