You can create a filter by dragging a selection rule from the toolbox and dropping it directly onto the Audience Designer workspace.
The new filter is named by default in accordance with the name of the selection rule. If a filter of that name already exists within the current audience, the newly-created filter is named ‘[Filter Name] 2’ (note that, if required, the numerical value can be incremented accordingly).
The new filter's Selection rule property is set to the rule that was dropped onto the workspace. The link between the block and selection rule is dynamic – that is, the block is always linked to the most up-to-date version of the selection rule. The selection rule’s name is shown in the filter, which is selected automatically.
Following the addition of a filter block, an asterisk is appended to the audience’s name displayed within the current tab, indicating that unsaved changes now exist.
