Yes, you could either use one of the custom fields within the reference template or use one of the pre-existing fields. So in your case, for example, in the Legal Rule or Regulation reference type you could use any custom fields (1 through 8; refer to attached image) and name it “Section Title”.
Refer to the Endnote training videofor further information on custom fields and reference types. Also helpful is the Endnote X7 Style Editing Guide (http://endnote.com/kb/131728)
