Having been put right re FAA rules, maybe I can offer some ideas re EASA rules.
In EASA land only one person can be PIC, and if a single pilot aeroplane only one pilot can log the hours unless operating commercially as multicrew which is done on things like King airs and smaller Citations.
As far as your Safey pilot hours go, if another pilot was logging the flight as PIC in FAA land, you cannot count them in EASA land unless the other pilot does not.
You can create a cloumn and record the flights but the hours cannot be counted towards any experience levels.
Hope this helps.
