Change theme on 50+ reports quick?

Is there an easy way to change the theme of my business' colortheme in all the reports, if there are changes needed, or do I have to download everyone and add the theme?

EDIT: For those searching and MS setting this as solution. There is no solution for worlds most obvious thing about using Themes. Create a theme to use in every report, but then You have to alter every 50-100+ reports later manually. Defeats the purpose of having a theme 😞

You may want to check Power BI REST API as it helps you to automate the process of downloading reports, applying themes, and re-publishing them using the REST API. This would require development skills to create and run scripts that utilize the API.

How is that even a possible solution. I would expect a simple method to alter all reports theme. Whats the use of a system were the company needs to download hundreds of reports to alter each an everyone. It some how makes the use of themes unusable.

But thanks for replying
