Marking and naming spots and surface characteristics is a feature in the TODO list (
http://forum.spaceengine.org/viewtopic.php?t=72 ) so it will certainly be implemented in future. There are mods available in the Steam workshop that use SE scenario scripts to mark main planetary nomenclatures for many objects as an example of what can be achieved with scripts.
What you ask, a planetary stereographic map with notable spots, it's not in the TODO list but given the scope and goals of the program it's quite possible that some version of that could be implemented in future.
