Import accounting transactions ESS job, is not setting "Include User Transaction Identifiers"

Summary:

When we run the Import accounting transactions ESS job which call Create Accounting job we would like the parameter "Include User Transaction Identifiers" set to Y by default. When I searched "Manage Enterprise Scheduler Job Definitions and Job Sets for Financial, Supply Chain Management, and Related Applications" under Global search and look for Create Accounting (XLAFSNAPRPT) ESS job I don't have the access to set the default value to Y from N for parameter "Include User Transaction Identifiers".

Question:
1) Can we update the seeded ESS job parameters?

2) Is there a way where I force the default value of the parameter on ESS job definition.
