You are making more complications than needed 
When I get non-pg material I run this test and save them all in a box with hand notation on the back of species and source. The method of saving a custom setting then gets used when cutting engraving etc. Then when there has been a successful cut (or engrave etc) I save that on the list I showed you. For most PG stuff I use the official settings. I do prefer a much higher LPI than most on engraving so I save those also noting speed and LPI (almost everything is full power)in the name. After several years the list is quite long but being alphabetical, not difficult.
