At the moment this app is all or nothing. If you want to have it automatically manage an Index Fund for you then it will ignore any existing amounts and rebalance the entire portfolio to be an index of the existing currencies.
Some people may not desire this. They may want to have an index of currencies but also be able to execute trades that aren't affected by an index fund's rebalancing.
Since there is currently no way to separate wallets/accounts on Coinbase Pro for an individual's account, the app will have to manage this.
The way this might be done is to allow a user to indicate what portions of each currency account is not dedicated to the index fund. Then you each time a rebalance was executed, it would have to refer to this allocation and act appropriately.
