Where has the Intercept ID gone?

I can no longer seem to find the Intercept ID - in the old interface it used to be available under the Test Intercept Menu Option. I note that under Embedded Data, adding an Intercept ID is still an option, so they must still exist. The reason I want it is so I can use it to set up a filter to exclude users who have seen an intercept in a different zone (project). I used to do this by filtering out the cookie for that intercept (which is essentially the intercept ID). So I guess an alternative question is, how do I identify the cookie that will be placed for a particular intercept? Answers to either or both of these questions would be amazing! Thank you!
