Finding the (raw) data for a specific event matching an event property

TL;DR:

It seems like there would be an easy to to find the data for a specific event, where the properties for the event are defined in the segmentation chart above.

Example:

I have an event called “points_transaction” where the property transaction_source can be from various sources (A, B, C, D, E...). 

I am trying to find the (raw) data for an event where transaction_source = “B”, but I might be doing it the hard way. 

1. Create a segmentation chart
2. Click a point on the graph
3. Select “View User Streams”
4. Pick any user
5. Filter by event = “points_transaction”
   1. It's not possible to filter for an event + property (where source = “B”), so finding the specific transaction I’m looking for can take a while as I go through them one at a time, looking for source = “B” 
6. Look at the event properties and note the time stamp for the desired event. 
7. Click user lookup in top right
8. Find the event again on the user’s event stream under user lookup. 
9. Switch event details view from “Info” to “Raw” to view the raw event data. 

Thanks for your ideas/recommendations.
