Allow ideas to be promoted to existing features

Thank you.  Completely missed that!!

Hi Shawn. When you click Promote to Feature, you will see the option to promote to a new or existing feature. Thanks!

The document you linked to says this:

Promote ideas to features

Once ready to promote, simply click on the green Promote button and choose the Promote to Feature option. You can choose to promote to any product for which you have rights and any release or parking lot within that product. When you promote an idea to a feature, a feature is created and a link is established between the idea and the feature. This ensures that a feature's origin is always accessible and that the users who submit and subscribe to ideas are automatically notified when an idea is implemented as a shipped feature.

I do not see where it talks about promoting to an existing feature.
