Add Global Alignment Controls for Power BI Matrix Values and Headers

Please add a global alignment setting for Matrix visuals that allows users to apply the same alignment, left, center, or right, to all measure columns at once.

This should apply to column headers, data values, subtotals, and grand totals.

Currently, value alignment often has to be configured individually under Specific column, which is very time consuming for matrices with many measures or field parameters.

A global alignment option would make matrix formatting much faster, more consistent, and easier to maintain.
