Dynamic filters

[ThomasWeppler]

Hi

I am trying to make measure satisfaction on diffrent customers. Each customer can have multiple tasks assigned to them and each task has multiple questionforms with diffrent satisfaction levels that I am trying to sum up. It looks like this.

The problem is that their are 1000s of small unimportant customers without any questionforms assinged to them.

I want the end user to be able to filter on the diffrent customers, but only see the customers in the filter which have answered a questionform.
I also would prefer to use PowerBI own filter to the right on the PowerBIsharepoint if that is possible. So far my solution has been to add two filters a hidden and a visible one. And only include the customers I need like this.

But I would prefer to only show the relevant customers dynamicly. I cannot add measures to powerBIs own filter and due to the direction of the relationship I cannot just remove all the customers without a satisfaction questionform so what should I do here?

Thanks for the quick response. I think that would remove some of the data that I need other places in the report.
What if I am willing to use the visualisation filter 

Then could I write a meassure that allows me only include the relevant customers?

@ThomasWeppler , I doubt you can pass value to source dynamically. You can use power query parameter for filtering the data you bring in
