So I modified one of the plugboard suggestions (from the sticky) slightly, so that the title of the book goes first, followed by a delineating character, followed by series info. Here's the plugboard formula:

{title} | {series:|| }{series_index:0>2s|[|]}

Here's sample output:

A Game of Thrones | A Song of Ice and Fire [01]

This is great (Thanks to everyone involved!), except for one little thing: when sending a single book (ie, not part of a series), I get this:

Book Title |


My question is, is there a method to make that delineating character conditional upon there actually being a series in the metadata? If so, pointers would be greatly appreciated.
