SSL Cloudflare and manual input?

Hi lads!

So far i’m having a blast of an experience with this CP, is fast, intuitive and looks hella sexy.

Just an odd question/QoL imp

When i use cloudflare SSL, do i need to input them (key & credentials) manually each time i make a new subdomain for the site? Or is there a setting i’m missing
Right know i’m reusing (key & credentials) Is that alright?

Thanks for you time!
