I do something similar. I have several pre-tied hooks/jigs with a 9-12 in leader and a loop knot on end. These I keep wrapped up on Jindy rigs (like pool noodles). The trolling rig itself has a snap swivel on bottom for the weight and leader attachment. Snap swivel on top for the top leader. All my rods have a snap swivel as well on the end on the line. In this manner, I can switch out leaders with different jigs as well as switch out weights. I never have to tie anything while on the water. I fish by myself most of the time, so I find it easier for me.
