Gantt Chart Date Format Configuration and Time Scale Adjustment

I'm stuck configuring the date format in OPC for the Gantt chart and columns.

OPC defaults to displaying the years as the actual calendar years (e.g., 2024, 2025, etc.).

I need to extract a version of the schedule that doesn't show the actual year but only a chronological numbering (Year 1, Year 2, etc.) in the Gantt legend and columns.

Is this possible ?

Additionally, where can we hide the time scale on the Gantt chart and add fields configured to achieve this Year 1, Year 2 setup? At least, this way, we won't see the years 2024, 2025, etc., on the time scale.
