Subcategory: General

Jira: ORG-23182

When Orientation=auto, default Gaps is 2, Margins is 5.
Setting may not be good when Orientation is not auto. User will need to adjust gap and margin.

When linked layer is 100% overlapped, Orientation=Auto mode supports Treat Each Source Graph as a Unit.

When source graphs' layer >1, and it is not 100% overlapped linking, It is not supported when Page Setup: Orientation is Auto.
