I think that just shows the ignorance of IO's with the online system. I am sure that they think they are being helpful and, in many cases i.e. Buriram, they have always done it together.
There is a perfectly good online system that does not need an IO to do a 90 day report when doing the extension. They don't at Jomtein, for example, because different desks deal with the 2 tasks.
