ASA format is very similar to APA format (which Word handles nicely)

One annoyance is with the Citation format that Word inserts with a {CITATION Smi05 \l 1033 ...} field and which shows as (Smith, 2005)

ASA format does not have a comma and it should be just (Smith 2005)

I've been using the "Convert to Static Text" popup, and editing the resulting text manually to delete the comma, but it would be a lot easier if I could maintain the link AND format the citation without the comma

So is there any way to change the citation format?
