How to combine all assignment's salary history in single view

During the salary planning period, we observed that salary history is not consistently stored under the active employee profiles but rather tied to individual assignments. This approach poses challenges, especially when employees transition between legal entities or have multiple assignments, as the lack of a consolidated salary history requires additional effort to verify merit eligibility for these cases this year. Hence we are looking at the feature or possibility to combine all salary histories across all assignment of the employee in single view.
