can we have child member name similar to parent member name.We want to see data rolledup with parent

Summary:

We have created Sales planning by Resource model and loaded data for Resource dimension with below hierarchy

All Resources

-Head of National sales (Parent) -500

-National Sales (Child) -1000

We aim to display both parent and child data rolled up together. For instance, "Head of National Sales - 1500". However, upon importing revenue data, it only aggregates the child data, resulting in "Head of National Sales - 1000".
So we tried giving name similar to parent but it is not accepting.

Thanks
