specify separator for composite columns

[capink]

Can calibre add an additional option to specify the separator for composite columns. I have a composite column that consolidates multiple series columns into one composite column called #series_composite. The issue I am having is that some series have commas, so when calibre tag browser splits using a comma, some series get incorrectly split into two or more series.

If calibre offers me the option to specify my own separator, I can change my template to use another separator (e.g. :::)

program:list_union(field('series'), field('#series2'), ':::')

Another related issue is using the following search:

#series_composite:#>1

which returns the following error:

I won't add the separator character because I have no idea what that would break, but I suspect it would be lot of things.

I am looking at the problem with count searches on composites.
