The challenge is report builder doesn't allow you to separate segments(in dimesion) like workspace...
You could create 2 rows of report snippets below each other in report builder where in report builder you select 2 segments each. Segment A -login complete, B organic visits, C from Marketing
row 1
check segment A and segment B -> UUID count(not sure if this metric is available in report builder)
row 2
check segment A and segment C -> UUID count(not sure if this metric is available in report builder)
