LACP for LAN Ports to enhance switching resilience

We love our Peplink Balance 30, but we would like to see LACP support on the LAN side. This would allow us to connect one LAN port to the top of our switch stack and another to the bottom, increasing our resilience in the event of any single switch failure. Right now, we cover it by leaving a cable hanging off the bottom switch so that we can quickly connect it to the peplink in the event of a failure, but enabling LACP would make this much easier. That, or at least supporting a static link aggregation group on the LAN side. (We tried this, to little success.)
