Using DIAdem to repeat an FFT function to multiple channels

Hello and excuse my newbie-ness. I ran a few queries here in the community and ended up in much more advanced posts than what I need. 

 

I have 30 or so channels imported to Diadem and I am applying a FFT analysis to each channel (accelerometer data). I am manually dropping each time domain channel (ex. Brkt_1_X) in to the function window, hitting calculate, then renaming the new frequency domain channel from AmplitudePeak to its final name (ex Brkt_1_X_FFT). 

 

I am able to record/create a script to do this, but it can only do this one specific channel, with the same specific name. I need to do this for 30 or so channels in the same .tdm file, with various names and naming conventions. I am looking for help figuring how to do this with Diadem built-in functions, or creating a script that can do this.
