Thank you for your response!
I am not understanding how you are suggesting to adjust the fixed asset - are you saying that you are creating sub-asset accounts and not hitting an expense account with the Depreciation Expense at all?  How would you do that - Debit sub-asset acct Depreciation and Credit Accum Depreciation?  That would increase the asset account...?
The Depreciation taken as expense = Credit to the Fixed Asset account
What about the accum depr acct would you just skip this?
