Notification Criteria Question

I am new to Gravity Forms and have been reading up on it through this site. I basically have two questions at this point.

(1) Is there a short code to add the template path to an image for the button? Just wondering if I can avoid hard coding the image path.

(2) One feature I really like is the notification criteria where you can specify a recipient based on a field's value.

However, on the site I am doing right now, I actually just need to do a round robin between two users so leads that come in from the form go back and forth between the two of them.

Does Gravity Forms support something like this?

Thanks for your help.

Thanks for your response. To elaborate on the 2nd question, I understand about the field values being used to send to certain admins.

Does that basically mean to accomplish a round robin, I'd need to use a hidden field where the value perhaps alternates after each submission? In other words, to do a true round robin, the value can't be user defined.

Does that make sense?

Thanks. Alternating the notification is what I was getting at. I thought perhaps you could run it off a hidden field, but I'll look into doing a customization. Thanks again for the help.
