Filter by Execution Defects(s)

Hi, we have just migrated to Zephyr Sqad, and I see that it's not possible to filter or search for test case with executions defectes in the execution navigator. 

I think this is a step back.. we use this to bulk change for block and unblock test cases linked to defect,, and it's som much more work to do this one by one..

How do you do this?
