Is it possible to run aptitude update only on a specific entry from sources.list?

Question

linux

There are quite a lot of sources in my sources.list (experimental, unstable, testing, debian-multimedia, google-chrome, etc.) and I'm somewhat lazy to edit the sources list every time I want to update, for example, only Mplayer or Google- chrome. Is it possible with aptitude's native (or third party) tools to "partially update" the list of packages?
PS mana and Google did not give an answer.
