How to add material at end of print job

So I have an issue (thats most likely related to my printer setup). When I attempt to print something sliced with canvas the palette 2s pro I have slices and splices perfectly fine except when the print makes it to the last maybe layer or so. The palette isnt adding enough material at the end of all the slices and due to this the filament makes it through the extruder and doesnt get pushed through the hotend for those last few layers.

So how would one go about adding something in the settings to tell it to make an additional amount of filament at the end?
