Reporting Depreciation individually for the members assets of the respective group assets

Our client has recently created group assets and they want to see a projection of depreciation of the member assets of the respective group assets. It seems oracle has no report to do the same in 12.1.3.

This is what i found.

What-if depreciation analysis report calculate depreciation on the value of group assets it will not consider the member assets.

Projected depreciation report only consider the independent assets for calculating the depreciation amount.

So, As per oracle functionality we cannot see the depreciation individually for the members assets of the respective group assets through Oracle standard reports.

Is there a solution for this ?
