@bcwoody The order that you entered the assets doesn't matter. As you said, for most CCA classes, the addition cost gets put into a pool, and the UCC is calculated based on the pool. When you sell/dispose of an asset, unless it's the last the last asset in the pool, the the pool will stay open and the UCC balance will persist until you do sell everything.
If you want to track depreciation more closely, you can use a program like QuickBooks, and use accounting methods to track your assets.
