Filter photos by shape works only for the vertices of the given shape. There should be an option to select all the photos that can see the shape along the edges and optionally also inside a closed shape.

Agisoft, please, give us a proper polygon selection tool, (or at least let us use any closed shape for selections as serves for dense points), you can't keep ignoring this simple tool requested for years, freehand is fast but is very imprecise.
Let us select photos by polygon, select triangles by polygon, select tie points by polygon, PLEASE
