Is there a way to split assets in Tax Books that are copied from Corporate Books.

I would like to know if there is a way to split assets in the Tax Books that are created in Corporate Books and copied over to Tax Books. We would need all the split assets to have the same cost which will sum up to the asset in Corporate Book. For example, an asset worth 40000 in Corporate Book, needs to be split into 2 units worth 20000 each in Tax Book. Kindly let me know if there are any other ways to achieve the split.
