customize 1a, 1b, 1c reference/bibliography type

Dear Sir/Madam,

I’m running into a small problem with the new feature in Endnote X3, that you can have multiple references within one bibliography item. Thus, the bibliography looks like:

[1] a) blabla; b) blabla; c) blabla

[2] blabla

Vary practical for journal like Angewandte Chemie.

However, I don’t seem to manage to insert a space/blank between the a) and the initials of the first author. If I insert a space/blank before the author in the bibliography style it inserts globally a space/blank into the whole bibliography, which causes the bibliography entries to be misaligned. It would be nice to make a separate style entry for references in nested bibliography entries.

Thanks and best,
