Eg: say my internal structure is this

Sequential(
(Conv2D_4): Conv2d(1, 16, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
(ReLU_4): ReLU()
(Conv2D_5): Conv2d(16, 32, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
(ReLU_5): ReLU()
)

and I want to add (Conv2D_3): Conv2d(1, 1, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
to the very first spot instead of the default last spot like so…

Sequential(
(Conv2D_3): Conv2d(1, 1, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
(Conv2D_4): Conv2d(1, 16, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
(ReLU_4): ReLU()
(Conv2D_5): Conv2d(16, 32, kernel_size=(4, 4), stride=(2, 2), padding=(1, 1))
(ReLU_5): ReLU()
)

How can I achieve this? Should I instead make a new empty sequential, add the layer first then copy over the previous 2 Conv2Ds and 2 ReLUs?
