Wrap up legend categories (positioned right/left) if the length is greater than 20 or 30

There is no provision in Power BI to wrap the categories of legend according to length or by one of these special characters (, / * ; - ). For example, I am creating a filled map where the length of the label is more than 50 in some cases - e.g. Oxford/AstraZeneca, Pfizer/BioNTech, Sinopharm/Beijing, Sputnik V. This is a problem in bar plots as well as in the case of filled map.

If there are more number of categories in legend and if the legend is positioned in top or bottom, not all the legends are visible. Therefore, there should be option to show legend in more than one row.
