Dicey, but definitely possible. There are also replacement connectors out there if needed, though not sure where you source them in the UK. We use outfits like Digikey here. I assume that the unit dropped from the mounting position with the cord attached, causing the damage.
You'll need to assess the condition of the traces on the board to see whether these have been torn away, and those must be dealt with very carefully and thoroughly first. If the 600 is like other TT units, the USB connector should have two lugs on the sides that anchor it to the board along with the power and data traces. If determined as repairable, then in the end, adhering the connector to the board may also be in order, rather than depending solely upon the solder joints to do the mechanical work.
You'll want someone with good board repair experience at the helm.
