Greetings from high weed pollen count Wetherby UK 
Ok ive been having extreme custom reporting filter frustration with Google analytics.
My objective was to set up a “custom” google analytics report that detailed:
- Referral traffic from external sights in one reporting tab
- Visitor generic traffic report including direct, search & referral traffic
e.g: http://i216.photobucket.com/albums/cc53/zymurgy_bucket/reporting-tabscopy.jpg
But Ive hit the provebial buffers 
Initailly i added an advanced filter as shown here:
but the advanced filters do not stick / save. As soon as you exit the custom report the advanced filter is cleared as shown here:
I then added a filter under a specific custom tab but the filter cascades into all the reporting tabs see below:
So my question is please…
“How do can you set up filters that effect the data in one reporting tab which does not cascade into the others”
Any insights welcome
