Spot Tracking

Question

I want to automate a spot, tracking across the floor with other than a direct FP to FP. Say a slight curve is required. Is there an effect I can use to move the spot in such a fashion?

I quickly made a demo of this, using no 3rd party software, just A3D, an SEM, and some focus palettes. 
 The broad strokes -- I had my rig in A3D, and my yellow brick road drawn out. 
 I made an SEM (Channel 11) and nested an A3D person object in it (from the library). 
 I recorded two focus palettes, the start point and end point of where the yellow brick road started and ended and recorded channel 11 in it. 
 I made one focus palette (FP 11) that contained my six overhead units (CH 1-6) and linked it to SEM 11. With SEM focus palettes or presets, be mindful of what data you record, if you need a Z offset, I would selectively record just the A3D Z height from the fixtures into the profile, so as to not have the fixtures have an X/Y offset. 
 In cue 1, channel 11 is at its start (FP1), channels 1-6 are at full in FP 11 (the tracking focus palette). 
 In cue 2, channel 11 is at the end point (FP2), channels 1-6 are unchanged. 
 Add cues/focus palettes if the path is non linear, but this shouldn't take much time at all to set up and with a well-calibrated A3D model, it works great. 
 Let me know if you need any additional info, I'm happy to share a more in-depth video of setting it up.
