Deposit adjustments and investment realized losses

So, this is a pretty simple suggestion - I'd be surprised if no one has ever brought this up. My orgs have active managed equity portfolios, so we frequently have to book proceeds of investment sales, resulting in a realized gain or loss. 


I've found that the easiest, quickest way to do this is to simply go to the desired cash account in Treasury, and book a deposit adjustment. This works great when the month's investment sales result in a realized gain - we just credit equity securities for the cost basis and credit realized gain/loss for the gain.


Now when sales result in a realized loss, this doesn't work so well, since deposit adjustments do not allow us to book the debit we'd need to the realized gain/loss account to make that transaction work. So, we have to do it awkwardly, creating a deposit adjustment for the cost basis, then creating a "payment" adjustment for the loss. That's 2 steps for something that should only require 1, in my opinion. Could do a JE, sure, but I prefer to not have to fire off a bunch of JEs for ordinary ins and outs of cash every month. Could also go through Deposits, but then I have to create the deposit and then add the payment - another 2-step process.


Is there something in business rules/configuration I've missed that would allow me to book a debit for that realized loss against the total proceeds, in a single deposit adjustment? If not, I'd like to suggest it.
