Moving Pre-seeded accounts

Summary:

Client wants to add a new parent between FCCS_Operating Income and FCCS_Gross Profit

Content (required):

Client would like to build P&L as such:

Is this possible in the primary hierarchy or does it need to be an alternate hierarchy?

Admin guide says If you want to create additional parents for seeded members you can create alternate hierarchies. You can "MOVE" the seeded member to the new parent members.

This confuses me. I was under the impression that parent/child relationships for seeded members could not be changed in the primary balance sheet/P&L. This statement above makes it sound like you can move the seeded members to an alternate hierarchy meaning you can change parent/child relationships in the primary hierarhcy.
