I'm not sure. If you want to add more rules to the set you can just add=20
them under that same section. ie.
[system=3D10]
add path acd0 group operator
add path acd0 mode 0660
add path 'da*' group operator
add path 'da*' mode 0660
add path 'ugen*' group operator
add path 'ugen*' mode 0660
add path 'ucom*' group operator
add path 'ucom*' mode 0660
=2D-=20
