Override TLP: overwrites the TLP color code associated with the feed entities with the one you set here. The selected TLP value is assigned to all the entities in the feed.
You can override the original or the current TLP color code of an (uploaded) entity, an incoming feed, or an outgoing feed.
TLP overrides have precedence over the original entity TLP value.
TLP overrides always supersede the original TLP value assigned to an entity, regardless of the TLP override being more or less restrictive than the original TLP value.
Filter TLP: only includes in the outgoing feed any entities flagged with the selected TLP color code. Entities without a set TLP color code do not show up in a filtered search.
