wintermute,

you can open up a CFD contract and sell into that the expact position you hold. You will then lock in your price and can hold until after the CGT discount kicks in.
every cent that goes up in the physical holings you go down in the CFD and the reverse applies.

I tried to do it for COE yeas ago but I held such a big position they couldnt find a counterparty. GDO has lots of shares on issue and unless you have a hige holding shouldnt be a problem
