Gain Loss Accounts by Major

Good afternoon. Can anyone tell me if there is functionality to allow for the following business requirement?

Our company runs more than Fixed Assets thru our Corp book.  We also have things like Marketing and Tenant Allowance.  For these non Fixed Asset majors, when we retire, we want the NBV written off to hit marketing expense or Tenant Allowance expense, not Disposal of Fixed Asset account.  The disposal of Fixed Asset account is only for gain or loss on true fixed assets.

Since the system lets us put different cost and accum accounts for various majors, we are looking to put different gain loss accounts also.
