Can we import our cert's if already achieved from previous resources?

So my question is I am a Red Hat Certified System Admin, and recently got my certification. I would like to know if I can add my cert to my profile in the kodekcloud.

Also, is there a way I can coninue my learning journey in the middle of the Journey like 100 days of DevOps?

As a new community member, I would appreciate your feedback/suggestion.

Thank you
