This feature would be especially helpful for modeling sales of assets. For example, selling a house at 100k, it’ll be nice to be able to specify the proceeds to route into Account A at 40% and Account B at 60%.

Besides this feature helping with planning, in some cases, it’s a requirement to have an accurate model - some assets or account types once sold require a percentage of the sale to be routed back to a tax advantaged account. For example, in Singapore, under certain conditions, a sale of a HDB lease requires the money used from Singapore’s CFP account type to be returned into the account. The US analogy would be if a house sold that was partially bought using funds from 401k, would require the sale proceeds to be returned to the 401k account
