Quick method to turn all FK controls to IK in Maya

I’m new to the Animation & Rigging Tools in Maya and have a scene with two Unreal Mannequin rigs that have some Mocap data that I’d like to clean up. The problem is that the legs are in FK and I want to switch the controllers for the entire timeline so that the feet controllers are all IK. I figured out Matching so that the IK controllers match the position of the FK but from what I can see, I can only do an IK switch on a single frame and would like to do it over the entire timeline.

Is there a way to do that that I might be missing? Any help would be greatly appreciated.

I’m using Maya 2016.

I figured it out. I managed to find the Rig_Settings by Right Clicking the IK MODE button and selecting ‘Select Leg Rig Settings’ and opening up the graph editor. Then it was a simple case of selecting all the keys for FK (0) and changing their value to IK.(1).
