Taxable transfer designation

I would like to have a new type of transaction for moving money between accounts. This would be used specifically for transferring money from a tax deferred account like an IRA to a regular brokerage or banking account. Call it something like “Taxable Transfer” or have a tickbox to indicate the transfer is taxable. This designation would be coded to have the incoming side of the transfer appear on the income tax reports as taxable income, but on other reports would show as a transfer between accounts. Currently, to have a transfer like this show up on the tax report requires me to add additional lines to the transfer transaction.
