Adding text to Bibliography Entrys

Hi,

I want to do something similar to Sybil, using Endnote X7, but I couldn’t find any solution. I am grouping multiple references as letters under the same number, and I though that one possibility would be to create the notes as for instance “Figure” reference type. This could work if I could define such “Figure” to not be numbered as a reference. Do you know if inserting a reference without numbering it, or lettering in this case, is possible?

In this example, the sentence “Oxidation of organolithiums:” would be defined as “Figure” reference type and not counted as a reference in the bibliography.

(4) Oxidation of organolithiums: (a) Möller, M.; Husemann, M.; Boche, G. J. Organomet. Chem. 2001, 624, 47-52. (b) Weber, B. Synthesis 1999, 1999, 1593-1606. (c) Barluenga, J.; Foubelo, F.; Fañanás, F. J.; Yus, M. Tetrahedron 1989, 45, 2183-2192.
