Multiple Animated Masks in Same Node

Is there a way to have two masks with keyframes in the same node in the color tab (I don't know Fusion)? I'm able to add keyframes to one mask per node, but how do I get a second "corrector" in the keyframes window so that I can animate a second mask in the same node? Is this possible in the color tab?

You can have two masks in one node, you just open the keyframes window and enable keyframing on each one. In the examples below, I have a Linear Power Window and a Curves Power Window, both keyframed.

You can animate multiple windows in the same node, but you can also animate in separate nodes and combine their output. Right-click in any empty area of the node graph to add a "key mixer" node and combine keys. Then you can animate each node independently, in cases where that's most appropriate.

That worked. Thanks!
