Permalinks – How To Capitalize First Letter Of Each Word In URL?

I am in the beginning phases of converting my existing HTML site over to WordPress and I just discovered a HUGE problem… My website has 200 + pages and every one of them have SEO friendly URLs and the first letter of every word in the URLs is capitalized. The problem is, when I copy/paste my existing URLs in WordPress’ permalinks it automatically makes the first letter of every word lowercase… For Instance:

My existing URLs are like this:

https://www.domainname.com/Page-Name.htm

Permalinks makes them like this:

https://www.domainname.com/page-name.php

(I’m converting my .htm pages to .php and using 301 redirects, by the way)

PLEASE tell me there is a way to fix this!

Any help or suggestions would be very much appreciated.

Thanks.
