sort of, Here's the two menu item names for saving with rights (i.e. the free ones)
Basic annotation Rights - "Annots:ReaderEnable"
form filling - "DIGSIG:UBDoc"
These still require user interaction.
I’m right to also think it’s impossible with an Action? Or a button with execute a menu command?
Yes, purposefully so. Adobe doesn't want people to be able to do it, unless they purchase a special server-application from them.
However, these right are not really necessary anymore, if the users have a relatively recent version of Reader.
