[Observium] Is there something like "bad_ifalias" ?

Hi everyone, the company where I work is an ISP and they have big routers like MX-960 and ASR-9010.This devices supports thousands of interfaces and we use it to connect to our customers.I would like to know whether is possible to ignore our customers interfaces based on ifAlias like we do with ifDesc (bad_if)?Thank you!
