Saving box & whisker plot as a template

Dear Experts. In excel 2024, I wish to save the style of a box and whisker plot (not any other plot) as a template, but the "save as template" is not actionable (it is in grey). I have a lot of box plots, and the default excel style is not good. So I want to create a plot as I wish it to be, save it as a template and then apply the template to all the other plots. Please help - thank you, David
