Hi Jack,
Yeah that part is definitely fixable; the good news is that it's a separate cable that incorporates just the headphone jack and the charging port so there's no soldering or specialized skills required to replace it.
Rather than repeat an entire answer, I'm just going to point you the the previous question where I responded with exactly the information you are looking for.

Sounds like you'd do well to pick up a couple of spares when you're ordering that charging port!
Good luck; let us know how it goes.
