How to import ADCS CRL into pfSense

[M3PH]

I'm trying to import the CRL from my Windows server 2012 R2 CA (Active directory Certificate Authority) but if I grab it from the certsrv page for my domain it gives it to me as a .crl file. If I open the file to see the details of the CRL it says it's been encoded in SHA256RSA format. pfSense obviously requires x.509 format. Is there anyway to convert the CRL to the right format? Do I need to change something in ADCS to make it work?

Thanks in advance for any thoughts you may have.
