You can add a new filter block to an audience by dragging a filter block from the Audience Blocks section within the toolbox. Doing so creates a new, unconfigured filter block within the workspace.
The new filter is selected automatically and, by default, is named ‘Filter’. If a filter named ‘Filter’ already exists within the current audience, the newly-created filter is named ‘Filter 2’ (note that, if required, the numerical value can be incremented accordingly).
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.
