I am trialling Endnote X9 with a view to converting our organisation to this rather than MS Word built in cross referencing.
Our in-house style uses letters to identify the citation. For example “in accordance with reference A, the manufacuturer …”. The corresponding bibliography entry would therefore be:
A. RUAG Technical Terms of Delivery - PT76 Primer, version 1.0.
I can create output and citation styles to give:
“in accordance with reference , the manufacuturer …”. and a bibliography entry of
 RUAG Technical Terms of Delivery - PT76 Primer, version 1.0.
But it appears that there is no way to create citations that are lettered (A-Z then AA, BB etc.)
Is there a simple way to to this or is it possible to add this feature?
Many thanks for you assistance
