Problem with created by and user permission

I'm trying the scheduler plugin

I've create some process in a project, but now i'm not user of that project anymore Issue are not created. I've to add me to project role users to have cheduled process running otherwise they will not trigger. My process has the correct fields , reporter too, but it seems it uses the uses that created the scheduled process to run it.

isn't it possible to change the "creator"?
