Now that you have explained some of the "finer details" of the context of the problem, it all adds up. I didn't like to say so earlier, but I thought the process you were trying to operate seemed like it was seriously ad hoc
and grossly inefficient - and that's putting it politely.
It didn't make any sense to me, so I asked myself "Under what conditions might it make sense?", and I came up with an answer similar to what you describe.
But seriously, inefficient/convoluted/problematic systems and business processes have a potentially high but often hidden cost, so they shouldn't be left unresolved, and people working in such environments are not necessarily going to be happy campers either, which could affect staff turnover (part of the hidden cost). Profitability is thus likely to be adversely affected. It's a wasteful use of resources.
I know that all doesn't help you with your immediate problem though.
Just a thought, where you say:
(I'm only one of several thousand users, and I do this in order to make these reports usable to others)
Have you already considered helping to get the problem resolved properly (i.e., via system and process improvement) by not
oiling the squeaky wheel any more? It could really
start squeaking then, particularly if management can't get the timely reporting information that they must have to manage their business. If management don't seem to care about the problem at the moment, it'll probably be because they don't perceive it to be a critical problem. You may well be inadvertently perpetuating
the problem by offering ad hoc
workarounds to it.
