Export / Import of Manually Created Colour Palettes In Chart Wizard

I have a custom colour palette, which I created using the Report Designer - Chart Wizard - Palettes Editor.

Does anyone know how to save a custom colour palette, so it can be seleted for new or other existing charts?

Is there a global setting somewhere for this?

I want to have a standard palette for all my reports / charts that is is keeping with our corporate branding colours.

Any help welcome.

Thank you in advance.

Regards

David
