If would be great if we could store a segment based on identfied visitors in any report and not only by rules in the segment builder.
Example 1) I use a funnel analysis and want to closer analyse all people who successfully passed the whole funnel or dropped out at a specific point. Then I would right click on the shown number of visitors and select "save as segment".
Example 2) I created any segment did a campaign path or stacking analysis and want a closer analysis for an group of visitors identified by this. Again -> right click on the number ans store as segment.
This would enhance the segmentation options drastically and would allow much mor in depth analysis of identified users.
