Suggestion: add option to bounce gambling bets and income (losses and wins) to a separate income counter to make gains/losses easier to track for countries which require gambling income to be reported separately, such as the US.
"Even if you don't receive a W-2G, you're required to report your gambling winnings as income. It's
important to keep documents such as wager statements and payment slips any time you gamble...
Professional gamblers report their winnings as business income. Casual gamblers report winnings
as "Other Income."
