UPDATED: You can use a little bit of sticky tac to put er' on the wall. No it isn't presliced for multicolor but its pretty easy to do. If you don't know how theres a video that may help. Another thing worth noting is for some reason a lot of yellow filaments I've seen and used are kinda see through and you can see the infill a bit so consider adding an extra wall and that might help a bit.
