Hi,
You can add them as custom materials. By adding them to the material database (check "Add material to database") you'll have it in the dropdown menu the next time you need it.
If you think some commonly used material is missing, let me know, it can be added to the default list as well.

Basswood & its weight can be added using the 'custom' feature at the bottom of the materials list.
