Ability to select Cost Tracking method by wallets

I have a number of different wallets/accounts, some which are used to hold crypto assets longer term and others used for day-to-day trading.

It would be great if I could select a group of wallets to use a Universal/Shared cost base and another group to use Wallet Based Cost Tracking. i.e one group of wallets would share the cost base and another group would be wallet based. This would allow better control of the assets to be included in the cost base.

In Australia a 50% CGT discount is provided for assets held for >12months. Allowing the selection of cost base by wallet would help in maximising the CGT discount for a group of long term wallets by sharing the cost base while being able to ensure a wallet that performs daily transactions does not utilise the same cost base.
