Hey whats up! Update your signature that you currently have?
Hmm I do not think I can update it because I do not know where the heart icon was found ._. If you made your signature maybe you can add it to the dreamies you obtained? If you had someone else make that for you .. it would be wise to ask them!
On the OTHER HAND.. if you are asking me if I can make you a NEW Signature. I can do that for you!
Just in case that is what you mean Here a link to my shop.

All you have to do is look through and read and fill out a form underneath the spoiler tab. The post is also found in the Retail part of the website.
Hope this helped!
