Description
Use case: when recording a point within a polygon, they can be automatically joined using relations, so that there is no need to manually select the parent feature.
This can be done using default values for relation reference field / using an expression (overlay_* functions) that finds parent feature based on the position of the point and then use its uuid as default value.

Research direction
No file or test is named. Start by locating the documentation section covering relations, default values, and overlay_* expressions, then verify the point-in-polygon workflow in QGIS. Done means documenting how to configure the relation reference field so a point automatically receives its parent polygon's UUID.
