Hello Kevin!
You could move it by clicking on the formula, then in the panel below, select the User Data menu. Below you will find the formula’s properties which will help you with the various movement you want. I’m not sure if this is the type of undulating you’re looking for, but I tried moving the waves as in the file attached by changing the Wave Height value each time from a positive to a negative value and vice versa, then recording it on the Timeline. I hope this is helpful, and let me know if you encounter any other problems.
