[Gmsh] use extruded lines to define new surfaces

Good afternoon,
I am trying to generate an hybrid mesh with a layer of prisms on a
wall (one of the faces). I can find out using visibility/tree browser
the id of the surfaces/lines generated by extrusion. Now I need to set
up the faces on the borders of my domain that go between the edges of
the extrusion and the opposite edges(the face on the foreground on the
picture attached), but I can't use the extruded lines (cannot be
selected). It makes sense since they are mesh lines rather than
geometry lines, but is there any way to convert them into geometry
lines? I could translate the lines but I'm using the extrude command
to generate the prisms and the extrusion is normal to the surface so
it won't match. I'm attaching a png image showing the lines of my
extruded layer and the lines defining the remaining of the box. And if
I set the lateral faces using the lines of the surface to be extruded,
I obviously get to superposed meshes, 4 layers of quads and triangles
connected to the same nodes
Best regards
Julien
