Add another save button when saving preset audience on Audience Studio

Currently, the only option on Audience Studio when creating a new audience is to save and launch the audience preset immediately. When users need to launch multiple interest audiences, they need to go back and forth between the Audience Studio and the Audience Launcher just to save another interest preset audience, which is not ideal. Therefore, it'd be great if there could be a button that allows to only save the audience and launch it later.
