Alexis apologize for responding too late.
I created the segment form flow report (below the description)
If I create a calculate metric to measure page transition I have 2 possbility
1) page views: in this case I count all page visited in session of user that perform that page transition
2 visits: in this case I count only visits where that transition occoured.
Neither 1 nor 2 give me the number of transition...
