You want to name a folder, say <Foo>, but then place files inside

No, I mean there are, say, export formats A, B and C. Assuming the
document file name is something like 'myData.data', export format A
should show a suggested name like 'myData.a'; format B should show a
suggested name like 'myData B Stuff'; format C should show a suggested
name like 'myData C Stuff'. In the latter cases, the name in the Save
panel's filename text field is the folder name, not a file name. (The
names of the files inside those folders is fixed.)
Not that this is really about folders. Another hypothetical example
might be exporting information from a contacts database as text files.
The export formats might be 'Names Only', 'Names & Addresses' and
'Names and Phone Numbers'; the corresponding suggested files names
might be 'myDatabase Names.txt', 'myDatabase Addresses.txt' and
'myDatabase Phones.txt', so that different exports do not by default
overwrite each other. File name suffixes are the only choice in this
case since the extension doesn't distinguish between them.

Can you use NSExportableTypes or NSExportableAs in Info.plist? It's
been a long time since I had to deal with that, but ISTR it will
handle the types popup for you (and hopefully the extension as well).
I didn't know about that either, but it doesn't exactly help here,
since handling the extension isn't the problem any more. (It was when
I first asked the question.)
Also, I'm trying to implement what appears to be a fairly new
recommendation in the HIG, which uses Export As… on the File menu to
replace Save a Copy As…, Save To…, or Save As… to a format the
application can't open. That implies keeping the export file formats
out of the Save As… dialog, and keeping document types out of the
Export As… dialog, which NSExportableTypes doesn't seem designed to do.
