Filter all items based on a selection on a visual

Hey guys!

I know the subject may seem as somenthing obvious or irrelevant, but I'll try to clarify on the thread.

Here's the cenario:

I'm working with a dataset containing all the approved travel requests from a certain period of time. Each request can have a single or several destinations for a single or several passengers. Based on this dataset, I created a simple visual containing a map so the manager can see what countries represents the most significant expense value and a table containing the detailed information for each of the requests so he can see what are the requests and who is traveling for each country. 

As I explained, each request can have multiple destinations, so when we interact with the map, only the line that have that specific destination appears on the table. What my manager requested is to alter the table, that have the detailed travel information, in a way that, when we click on a country on the map, not only the single line of the travel request appear, but all the lines that are related to the request that have the selected destination.

To help you guys understand what I'm trying to accomplish, here's an example from my dash:

This is the map and the table as is.

Suppose I want to see who travelled to Turkey, so I click on the point on the map 

Basically we have 3 different requests that went to Turkey. Now, what I need (using request 20030 as an example) is to bring, when I click on Turkey, all the legs for each request, that would look something like below (remembering that I manually filterd only the request 20030).

As we can see, the request 20030 have 3 different legs, having one of them going to Turkey. The same happens for the other 2 request as shown in the second picture, so the result I need is the table from the second picture showing not 3, but 9 lines (3 lines for each request id).

At this point, I'm considering reporting this to my manager as something impossible to achieve on PBI, so this community is my last hope. If someone have any clues to how I could make this work, I'd really apreciate the input.

I wish to all a merry Christmas (a little late) and a happy and prosper new year.
