is there anything that allows you to decide, when do you want the flanger to make an effect and when to not? Or can the effect in the track be automated so, that the effect would both decrease or increase just like you can adjust the volume in an automation clip?
You should be able to 'Edit Events' for the Flangers Mix Level , to the right of the effects name in the FX slots panel in the main Mixer window.
