is it possible to "plugin" additional local checks?

dcm2niix adds field ConversionSoftwareVersion into sidecar .json, which is great since it allows to verify that all data files were converted using the same version, which could be "career saving" ;)

Unfortunately this field is not a part of BIDS specification, so I cannot probably suggest enhancing bids-validator itself. So I wondered if may be you see an easy way to setup locally additional checks which bids-validator would pick up.

thanks in advance for ideas
