Load materials from library with Java API

Hello COMSOL aficianados,
We are working with the Java API for COMSOL here. Let's say you want to load the material copper into your model. It seems, according to the manual, that the only way to get all the material properties is to define them all yourself using e.g.:
myModel.material().create("mat1");
myModel.material("mat1").name("Material name");
myModel.material("mat1").set("roughness",0.1);
myModel.material("mat1").set("shininess",200);
myModel.material("mat1").propertyGroup("def").set("density","8700[kg/m^3]");
etc. ad nauseum for every single material property.
My question - is there a way to just do, using the API, what I would do in the GUI, which is to load the pre-defined material from the COMSOL materials library? Something like:
myModel.material().loadFromLibrary("copper")
and that would automatically just load up everything into the model?

On the suggestion of Mia Johansson at COMSOL, I have submitted this as a support case:
www.comsol.com/support/case/1306339/
I should note that this question applies to LiveLink for MATLAB too, not just the Java API.

From COMSOL support today:
I think the way we'll deal with it for now is to write a separate Java library that basically returns COMSOL materials as objects (essentially re-implementing the materials library in Java) so that we only have to write it once. Because we'll be using these materials in many Java files.
Dear Geoff,
I agree with you, it would be nice if there was a more compact notation for this in the Java API. Unfortunately there is not at this time. The only simplification I guess you could do is to delete the rows which set material parameters which you do not currently use in the model. But on the other hand they may come in handy if you later on develop the model further and add more physics nodes, so really I think the best is just to leave this part of the code "as is" when you save as .java or .m file from the graphical user interface.
Let me know if anything is unclear or if you have any further questions.
Best Regards,
Anna Juhasz
