No document at the 18th Circuit collection of documents, but this entry appears on the docket sheet. I looked at the governor's office website for a copy of this (in the executive orders area), and did not see any change at 12-279, or in the collection of EO's for this year.
The original assignment, 2012-72
is not titled "Designation of Assistant State Attorney," but is in the nature of "Assigning a State Attorney." Corey is the assigned state attorney. She was given the power, under the original EO, to designate assistant state attorneys and investigators.
All that to support my speculation that this amended designation originates with Corey. It is probably nothing more than designating additional assistant state attorneys for trial duty, or specifying existing designated assistant state attorneys for trial duty.
