a possible way to set the name of the bundled css file in dist folder

Hey, i want to change the name of the css file that got bundled in dist folder from index.css to any name i want.
like here in this image i want to change the name of the bundled css file to rts.css.
can I do this?

Start by examining how the bundled CSS output is generated and named in the dist folder, focusing on the reported index.css artifact. Determine whether the existing configuration or documentation exposes a custom name, and consider the work complete when a user can reliably produce the requested rts.css filename.
