How to assign & spooljoin filament from PrusaConnect

When the XL originally shipped, filament join was in the future, but came with a firmware update.  I have been under the impression that you had to be at the printer to set it up.  Anyway I have found the “hidden” feature in prusaconnect that lets you do this remotely. 

Basic documentation of how to do this on the Printer is found here: https://help.prusa3d.com/article/tools-mapping-and-filament-mapping-xl-mmu3_732461

1.  You start out as always, sending your gcode to Connect
   
   
    
2. However you CANT schedule your print at this time, you must ONLY COPY it to the printer
   
   
    
3. Next in prusaslicer you go to the Connect tab
   
   
    
4. You have to wait until your g-code is uploaded to your printer (I think)
   
   
    
5. Next You MAY have to click HERE (Yes its a button)
   
   
    
6. Then click on “Printer Files” (note this is different that “Connect Files” , Connect files are files in the cloud, Printer files are files ON your printer)
   
   
    
7. Find your file (most likely the one on the top) NOW DONT RIGHT CLICK, but just click on your file
   
   
    
8. You are almost there, YOU HAVE TO SCROLL DOWN, you cant see what you want
   
   
    
9. You found it!
   
   
    
10. You now click on each of the G-Code filaments on the left, and you can reassign them and/or join them on the right
