We can do Transfers from Bank Accounts to Asset, Liability and Equity Accounts by ensuring that the Show all accounts box is ticked.
However, it is not possible to do this when setting up a rule regarding the transfer. In the Rule set up window it is only possible to set the transfer to (or from if it is money in) a bank account. There is no tick box to choose all accounts and bank accounts are the only accounts that come up in the selection drop down.
Considering this is a very common transaction for Drawings and Payments to Liabilities, it would be really good to be able to create a transfer rule. The only work around availabe at the moment is to create a payment. A transfer option would be much better.
