When you need to load consent to the consent centre the only way one can currently do this in CI-J is via a marketing list. Yet if you need to target a subset of existing users you do this via a creating a targeted segment. If you need to add/remove consent for this subset of users we are currently unable to target segments from Real time (only outbound segment membership can be added to a marketing list currently).

It is therefore necessary to allow users to create a marketing list based on (Real time) segment membership to enable users to efficiently manage consent.

Importing and exporting spreadsheets should not be the default method to manage bulk consent.
