You should be able to just add anything with a Group ID to it. Like a link to preview the HIT or to accept the HIT. You can even grab them from the HIT exports that are posted here. Or if you try to click on a HIT in HIT Finder or something and it is gone, you should have these two buttons. "Once" will try to collect that HIT and stop when it gets one (good for surveys.) "Panda" will just try to keep grabbing as many of that HIT as it can (good for batches.)
I've got the two buttons. Thanks for explaining what they mean.
