Need help wiring a bypass switch for pool pump circuit

I have a pool pump that plugs into a GFCI protected outlet. There is a subpanel, which I ran three conductors, a black, green, and white 12awg in 1/2" liquid tight flex conduit from subpanel to a timer. From the timer I ran the same conduit and wire to a gfci outlet.

I have ran into situations where I need to bypass the timer when there are certain chemicals in and I need to run it for a day or two straight, or if I need to backwash or something during an OFF cycle on the timer.

How would I do this? I read that basically all that needs to be done is split the circuit in two, before the timer, and put the second circuit on a switch. Then combine the two split circuits back into one.

Could I just insert a weather box with switch before the timer and create two circuits inside the light switch with pigtails...one circuit goes straight to the timer and the other circuit taps the light switch... and leaving the new weather box would be two blacks, two whites, two greens into the timer. One set of wires would tap the timer. The wires coming out of the timer would then be pigtailed to the switch wires. I hope that makes sense. I've attached my current and proposed setups. The goal is for me to flip the switch when I want it to run at my own discretion and it not be a hazard if the timer flips on with the switch on.

Yes, your diagram is correct. You are just paralleling the switch and pool timer.

You could also temporarily remove the OFF tripper like I do for my pool.
