Goals to impact on net worth rather than account balance

In case i want to increase my goal balance by a certain amount i’d want to increase a liability (with a net worth impact) rather than modifying my current balance by a transfer that doesn’t necessarily happen.

For istance:

Bank balance: 4000€
Savings for my goal: 500€

Money coach transfers 500€ from bank balance to goal and shows a wrong current balance for my bank account (since it’s still 4000€, just 3500€ available for expense).

Thanks!
