Yes, you can run that jumper from C11 to C10, it’s all the same node. But I was expecting you to run these jumpers on the solder side of the board. Use very fine wire (i use 30 gauge), which you can acquire from the inside of old vga cables or something similar. These traces should be run close to the circuit board surface. You should just bend up the mix pot and solder the wire to the correct pad and then bend the pot back down on top of the wire and insulation paper. But to answer your question, you can run the jumper from anywhere on that node.
The resistor should also be placed on the solder side of the board.
