How to add sequences to my account?

[Lenticular Clouds]

I've known about this site for a while and had created much till today. I wrote a few bits of songs, (, ). However, only then did I make this account, my first and only. Is there any way for me to incorporate these and a few other sequences into "my sequences"

I'm really sorry if this post is in the wrong place. Thank you for your time. Also any advice with my doodle songs would be really appreciated

You can remix them and they will be added to your account.

Remix? Like copy and paste the notes into a new sequence? Thanks
