Is it possible in Wordpress to merge css files into one file on the fly?

Question

css

I don't know what it's called correctly. The site was made up by "modules", that is, each functional block is placed in a separate file (like header.php), each block has its own css file (header.css, etc.).
With this approach, it is easy to duplicate / move almost any block to another page by including only 2 files (php and css).
But on some pages, the number of included css files reaches 10-15 pieces.
Is it possible to combine these files on the fly using WP tools, for example, in style.css, and then include them?

What caching plugin are you using?
It seems that in WP Total Cache you can check the box "combine styles and scripts into one file".
