Do you not just start the decent from circuit altitude earlier to pick up the profile?
You could, but that may mean you are intercepting final near the 500ft mark (assuming you tightened the whole lot up), company policy is fairly strict on what happens from 500ft (thanks CASA and the stable approach policy) and if you miss judged it you would be forced to go-around and try again. A lot of the flying is set out in the company manuals and any deviation from those manuals is frowned upon.
