Building two skirts in dual extruder for preextrusion

I know in oozing prevention a skirt is generated for each extruder, but after a skirt is done I want the extruder to print the whole layer and not to change extruder and print the other skirt.

Someone know how to do it?

I still don´t know how to prime the second extruder just before it prints the support. The first extruder gets primed well doing the skirt in oozing prevention.
Any help?

I want to prime all the layers and do it when the first extruder has finished printing the current layer and the second extruder starts to do his printing. I ´ve tried to print a prime tower as a first or second part but the extruder doesn´t follow the ordinal number, it makes 1-2-2-1 printing the nearest part. I also have tried custom output (start, tool change, end ...) without sucess.

I have found the Tommullholland topic "Source code change - dual extrusion" for the extrusor ordering, I will try if this change can help me.
