Forcing Autosaves on Event Triggers - Doable or not?

Basically the title, I haven't gotten down to any actual code with this idea yet, but I wanted to know if it is possible to force a save without player input with the way Essentials handles saves.

this is quite simple.
if you want to make an event that saves, first you should simply make an event, and then you add an event command, on the third page on the bottom right you should find a button with: "Script...", if you click it you should get an input box.
in that box you write:
pbSave

and thats it, this will not display any text or give a notification, but it simply saves.

be sure to say if it works :)

*note: make sure the "S" in pbSave is a capital letter, if it isn't it will cause an error if the event is played
