How to incorporate depreciation buckets in asset

We need to establish a tax book for the UK, incorporating depreciation "buckets" determined by the net book value of each bucket. For example, as of 12/31/21, the net tax value of the bucket stood at 10,790, resulting in an 18% deduction of 1,942. Moving into 2022, with a new net tax value of 8,848, we anticipate a depreciation expense of 1,593 for the year, following the same principle for subsequent periods. It is important to note that these "buckets" should not expand according to the aforementioned general rules; however, they may undergo changes if the assets within them are disposed of.
