Two Digital Sidecars?

[moogboy]

Hi all. My team is getting ready to do the electrical bits for our robot, and based on current design we need more than 10 PWM outputs. Thus, we need to know whether it is within the rules to use two digital sidecars. Any insight?

[R60] says "Every relay module, servo, and PWM speed controller shall be connected via PWM cable to the Digital Sidecar and be controlled by signals provided from the cRIO via the Digital Sidecar. They shall not be controlled by signals from any other source."
My interpretation of "the Digital Sidecar" is that we can only use one, but I am very interested in someone disproving my hypothesis.
