I would like to use responses to four different items in my survey and create a new segment based on those responses for reporting purposes. Is that possible in SG?
Short answer, yes.
When adding a new segment, you can choose “Create Advanced Segment”. From there you can click on the Edit Logic button. Using the standar logic with Add condition and (if the logic you need is complex) Add Group links should allow you to create almost any segment you could want.
If you use the ‘Create Advanced Segment’ option from the drop-down menu in the screenshot:
You will be able to combine questions to build more complex rules for your segments.
I hope this helps!
