Looking for a more simple way for a user to create a child work item from a parent work item

The basic functionality of what I am looking for is available in the Links tab and field.  However, I am looking for a way to stream line the creation (maybe addition) of child work items of a specific work item type.  Ideally I am looking to create a link field who's add button is "Add Child" or "Add [specific child WI type]".  Then the create work item dialog box opens for filling in.  Click OK and repeat.

Context: The customer wants to have a Peer Review work item type to hold basic peer review information.  Each comment during a peer review must be captured along with other attributes associated with it.  The current solution is to create a Comment work item type.  Instances of this work item type can be children of the Peer Review.  The number of comments for each peer review is unknown and need to be created dynamically during the peer review - generally by a moderator.  Creating comments quickly and efficiently becomes important, hence looking for a quicker way to create linked child work items.

Thanks
