Sync Holdings as Separate Accounts to Lunch Money

The customer, Mark, is requesting a new feature for Lunch Flow. When connecting a DEGIRO account, Lunch Flow currently displays both 'cash' and 'holding' balances. The 'holding' balance represents the investment portfolio's value. However, only the 'cash' balance is currently sent to Lunch Money. Mark requests that the 'holding' balances also be sent to Lunch Money. He specifically prefers that each individual holding be mapped to a separate account within Lunch Money, in addition to the existing cash account.
