Eliminate 100% Data Source Total Input & Adjusted value for the proportional method

We understand the FCC out of the box Elimination rule checks If the amount proportionalized by either entity is less than 100%, then only the lowest proportional amount is eliminated because only the lowest proportionalized amount is controlled in common. Therefore an eliminated amount cannot exceed the proportionalized amount under any circumstances. However Our client have a requirement to Eliminate 100% Data Source Total Input & Adjusted value for the proportional method. Sample working for 50% Proportional using Data Source member as follows.

Appreciate any help on the above Intercompany Elimination requirement.
