DrChiper,
Bookmarks offering a quick and automatic "jump to bookmarked page/content" is how I remember the feature operating.
The built-in calibre viewer is a light e-reader, providing basic functionality, not including some of the more recent e-reader software features and benefits. One of those being annotation support. You may have to find more feature rich e-reader software to do what you want on the PC. Perhaps one of the programs you're already using for hardware offers a PC version?
Unfortunately I don't know of any software that offers PC and Android versions, so I cannot make a recommendation.
