To some extent, that question takes me into technical waters I am not qualified to go into, so I won't answer it in detail.
This hierarchical organization, programs and sub-activities and so on, that I was talking about, on the face of it...if that's the information structure that parliamentarians are using, then it would make sense to make the votes as closely related to that as possible, just intuitively. So if you structured the votes in the same way, or using the same language to the extent possible, to me that would make sense.
The only thing I would say is that I'm not sure you even need a structure of multiple votes to do what Parliament currently does with the estimates, which is to concur in them normally.
