Import material library

Hi. Is there an easy way to import absorption coefficients of typical materials to the pachyderm material library without having to insert them all by hand with the sliders or input fields within the pachyderm user interface? I collect most absorbers that I use for different applications in an excel sheet but I could not find a material file from pachyderm that I could paste this information in. Alternatively, is there a bigger material library especially for pachyderm (including information for the angle of incidence) that I can download?
