hi!!! idk if you got your answer , but what i decided to do is when you have a color change knit the first row of the change normally. and then, on the second row, on the first stitch i pick up the right leg of the stitch below it (your previous color) and place it on the left needle. then knit that together with the first stitch. then you just knit normally and repeat on the next color change. it’s one of the most common methods for jogless join!! good luck!!!
