Trade in and purchase of captial assets with loan creation but no 1st payment.

Please make it so that capital assets can be traded in on a newer ones without having to use general journal entries! So frustrating! A lot of the time we purchase a piece of equipment, trade in our old one for the new one, set up a loan but don't actually make the 1st payment on the loan until later. If I don't use the transaction window then my asset list doesn't remove the traded in equipment OR add the new equipment. So by having to use general journal entries all the time, my capital asset list is never correct.
