The answer to your question is yes. To summarise,

intially the suffix needs to start from

Code:

A, B, C, ..., Z

so that the 'processed' output (or as you call export) looks like

Code:

0580937A, 0580937B, 0580937C, ... 0580937Z

and when the suffix reaches Z then 'processed' output looks need to appear as

Code:

580937AA, 580937AB, 580937AC, ... , 580937AZ, 580937BA, ...  580937ZZ

i.e. in brief

Code:

0580937A, 0580937B, ..., 0580937Z, 580937AA, 580937AB, ...  580937ZZ

hope I'm making sense with my query.
