I would use eventDetail if you want to record it within PREMIS.  
eventDetail says it's not intended to be processed by machine and can be
used for any additional information about an event (I suppose you could
consider SIP submission an event). Better would probably be to store it
outside of PREMIS in something like an authority file/agent information
file.
