Post Processing G Code

Straight up, this is more a slicer than a machine issue.

I’m wanting to print a “Purdue coaster” as a present for a Purdue grad. I’ve found the file on Thingiverse, but the summary on that website calls for color changes at layer 11, layer 17, layer 22, and layer 26.
Cura allows a post processing filament change and modifying Gcode but, I can only figure out how to make one filament change at one layer, not multiple color changes as the print progresses.

Any good ideas?

Thanks in advance

You have to add click + and re-add it for each layer change…so you have to add the code 4 times (filament change), then change the layer for each one & re-slice.
