[Observium] Calix E7-2 port disabling

I have 14 Calix E7-2 OLTs in this environment that I want to monitor. The first two I added to Observium(PE 5447) showed up with over 1000 ports each. I'd like to disable polling/alerting on all but a handful of ports on each of these devices. I used the "All" button on the device's Ports tab to get this done, but it only disables the first 333 ports. Same behavior on the second OLT. The remaining 900+ ports are all still enabled for polling. Manually selecting the slider for 50 or so of the remaining ports to disable them fails to take effect after clicking "Save".

Is there a way to disable the remaining ports, then enable the few that I am interested in?

Thanks Doug
