Change permalinks

Can I change/run a script on a WordPress page with this plugin so that all permalinks are changed at once or do you have to change them one-by-one?

Eg: I have a page where the links are like: https://www.mysite0550.com/clients/windows but I want them to be called like: https://www.mysite0550.com/sevices/windows so in other words I want to change all clients to services. Thanks for the tips..
