Auto-Creation - Creator and step revisit issue

Hello,

I've got a BP that has a step in it that auto-creates another BP record. The destination BP can be used by itself by other creators or through auto-creation. It all works great. Except for one thing... The creator is required on the auto-creation setup. I'm not allowed to select a group for obvious reasons. I selected the Company Administrator. I selected the desired group for assignees. The trouble comes in when we do step revisiting where they are dynamically pre-assigned to the creator. Is there a different way to get the creator to be the same as the creator
