So, I guess we have to trust you and assume that you won't systematically be making this kind of request. You could simply tell the parties that, from now on, it would be simpler if they just provided the supporting documentation. The issue is the turnaround time; we are given a certain amount of time to submit our return. If you intend to ask us to provide everything in one shot… As you know, the expenses are more important.
