Is there any possibility to use two independent counters within the chemnum package? I would like to label (by replacing the tags in my .eps file) substances in reactions and steps in catalytic cycles with different styles. The former with simple numbers, and the latter with letters (A,B,C,...).
If I only change the style of numbering before replacing the tags, I don't get a new counter. So if I already showed the compounds 1,2,3 and now want to describe a step in a cycle, chemnum will replace the tag with D instead of the favoured (wanted!) A.
chemnumonly has one counter so if you don't want to declare the labels in the preamble (which I wouldn't want to do either) you probably have to reset the counter for the second set... I may be able to add something tochemnum, though. I'll have a look... – cgnieder May 04 '15 at 19:16
