Edit inserted Dynamic Component...help

[bjack56]

Using Sketchup 8 Pro.
I found the perfect DC model for my project.
It is lap siding with ht & length Options.

Not a total Noob (except for DC components) & tried everything I can think of to modify in my model, but no luck?

How do I cut openings for doors & windows in a Dynamic Component???????
