Question on workitem editor presentations

For my workitem I have a section called planning.  I created 3 new fields that need to be added to the section"planning".  They want these 3 fields in the 'planning section' but I need to separate these 3 fields from the rest of the fields in planning and Identify those fields with a label.  When you create a section, there is name that goes with the section, well I can't create a section within a section and I can use a line separator or separator attribute but I need to identify what these 3 fields are for which a line separator/separator does not contain a title.

So in the planning section I need to do this

Title

Field 1

Field 2

Field 3

and separate with the other fields in the planning section.  Is there a way I can do this?  I need to group these 3 fields together and have a title identifying what these are....?

Thank You,
