Sadly, Hobopolis progress doesn't have any tracking preferences. Hobopolis progress can be tracked much like the War can approximately by image: otherimages/hobopolis/townsquare1.gif (freshly minted) through 25.gif (boss up) and 26.gif (closed). Same goes for the side areas, which have 12 images: 0 is no progress, 1-9 10% to 90% progress, 10 is boss up, 11 is closed. The sewers have a series of images as well, but these don't track progress directly, instead corresponding to grates and valves opened. There's also no single image for "completed sewer", but the presence of "deeper.gif" can be used in its place.
