Feature Request: Ability to exclude certain columns

[flyingstoat]

There are certain PII columns like customers.name, customers.address, and customer.phone which to be GDPR compliant, require a justification for their storage. There isn't a justification in my case. I need the products, prices and subscriptions, but that all.

I could write a trigger which redacts the information, but it still means i would be processing and storing.

Ideally, I would like the ability to whitelist the data I need to be synced, or exclude certain PII fields.
