A way you might be able to manage the initial setup.
Sonar allows you to hide console strips. Let's say you want to insert a particular compressor to tracks 1,3,7,9
Hide all tracks till only those 4 are open. Add whichever plugins you want in all of them by placing a plugin in the first of the visible strips, hold down ctrl while click and drag to the networking 3 strips.
Then unhide strips and leave showing the ones you next want to add plugins too and gradually build up your setup that way. That's the only way I can think of to do what you want.
