Add fields dynamically in Encrypt field snap

Hi Team,

The community is amazing and very helpful. Kudos to everyone behind it.

I'm working on encrypting certain fields(PII) coming from SFDC sources and using encrypt field snap for the same. For that I'm having to add the fields manually in the snap. But I want to develop a generic pipeline for multiple source objects from SFDC where the fields to be encrypted would be varying(I can store those details of objects and fields in a file or config table to identify them dynamically). I'm not able to find an efficient way for the same as the fields tab in encrypt field snap is not having option to create an expression, leaving with no option except adding them manually. I'd appreciate if anyone could help me understand if there's a way I can achieve that.

Thanks in advance !
