I have changed our boards to the main recommendations so far and now I hit some wall. Our QC is testing away a new internal release and getting back with the issues. But they create a new card in the "Test" list containing a check list with all the potential bugs they found, around 10-12 items.

Should they rather create single cards for each issue and push it into the inbox? I feel somehow its going against the system to summarize a dozen points in a kind of "Test Report Card".
