Chain seams selection for meshes

Hello, when i proceed to unwrap a NURBS geometry it is possible to do a chain selection of the seams. But this option seems to be missing when unwrapping polygonal meshes.
Even if one mesh has few polygons, manually selecting every edge could be boring.

Is there a way to achieve a simple chain selection for meshes?
Maybe a shortcut?

A script, a plugin?
Something like: Click on edge (select a seam) if the angle between this edge and other edges connected to it, is less than user defined angle then automatically select this other edge and go on with the chain.
