Using a filter that takes into account multiple string data

[Anonymous]

Hi, I'm looking to add a filter for the sources that our data comes from. The issue i have is sometimes we can have multiple sources so i'm looking for a measure that would take that into account.

I've attached an image showing multiple sources.

I'd kindly suggest being more to the point since your description is a bit too vague. Please get familiar with this first: https://community.powerbi.com/t5/DAX-Commands-and-Tips/How-to-Get-Your-Question-Answered-Quickly/td-...

Sincere apologies Sir, 

I'll try to add more detail to my question. I'm looking to use the sources field as a slicer, however sometimes we have multiple sources so i'm looking for the slicer to take this into account. For example, the slicer option of IMB would include IMB/Closed as well as just IMB. I have attached more images, including the tables showing my issue.
