Don't remove CNAME

[lmk123]

I use Webpack to build my project and output to ./dist directory. I have a CNAME file in my gh-pages, but it don't in the ./dist directory after Webapack build, so when I run gh-pages -d dist, it remove my CNAME.

I can run gh-pages -d dist -a but I use Long-term Caching, so if I added -a, the file will be more and more in the gh-pages.

Can you add an option that don't remove the CNAME file?
