Track original source

Can’t you create a hidden field in your form, dynamically populate it, ans then use that as a label in your feed?

The only related dynamically populated field is the {referrer} tag and it only shows the url they came from just before. It’s like I can track what adjacent room they came from, but which door or other rooms they came through is lost on me.

Let me ponder this and get back to you.

Your best bet is to modify the values programmatically.

There’s some filters in the plugin that will allow you to pass values to Google Analytics programmatically. Unfortunately they are not documented yet, but you can find the code here.

I’m not sure of your requirements, but you can perhaps grab a cookie or PHP server value and inject it into one of those filters based on the form.
