Bookmark within Konsole

Within Konsole, we sometimes run program with very long output, especially when compiling stuff, or, on Gentoo, emerging packages.
We may even run several such programs in succession, so that the history can be very long (assuming the setting is history=unlimited).
Now, is often becomes very difficult to scroll back to a specific point, e.g. to the starting point of a specific compile element.

It'd be useful to have the possibility to set temporary bookmarks within a single konsole window, so that we could easily scroll back to a specific point within the history.
