Can the outputs of a substance/procedural material be saved as textures?

We generate a lot of different procedural materials at run-time based on player settings. They take a long time to generate (1-2s x dozens). The artists are working on making them less complex, but I suspect it will not be enough, so I would like to be able to cache them between sessions. However, from what I can tell, there does not appear to be a way to read the outputs (e.g. diffuse and normal maps) of a generated substance at run-time. Can anyone confirm?

After emailing with the Substance guys: they cannot, but this is planned for a future version.

Actually, you can. Right click the material, export bitmaps. Seems to have worked for me.
