Hello,
Before I go on, this is tricky to explain so please bear with me!
So.... here is the scenario I am trying to record monitor....
1) User visits page A (e.g. product)
2) User does not visit page B (e.g. purchased)
3) User returns to the website and visits page C (e.g landing page)
My aim is to find out how many users visited a specific product page, did not purchase the product, and then returned to the website (this either in the same visit or in a future one). Though this is easy to create as a segment..... I have found myself restricted to the date range in the top right of the freeform table.

What I would like to do is only have step 3 driven by the date range in the top right and have steps 1-2 having occurred within the last 30 days of the day on which step 3 happened.
Hope I have made myself clear... if not... please do ask questions!
Thanks in advance,
Max
