Identifying Audit Logs

1. What is the problem? Be very detailed.
Exporting forms with audit enabled leads to many files named audit.csv. The submission csv has a field entitled "meta-audit" and all the entries are audit.csv. How can I see which audit log file belongs to which submission?

2. What app or server are you using and on what device and operating system? Include version numbers.
ODK collect v1.28.4
ODK Central 1.0(? can't find the version number in the web interface)

3. What you have you tried to fix the problem?
I've read the docs looking for an audit log parameter that might help but could not find one.

4. What steps can we take to reproduce the problem?
Enable auditing, submit more than one completed form and download submissions.

5. Anything else we should know or have? If you have a test form or screenshots or logs, attach below.
ODK is fantastic (but I'm sure you already knew that).

I don't think it should matter for this question, but in the future if you want to check the Central version you can just add /version.txt to the URL.

I haven't used audit in Central but the docs note:

Central will export a CSV with audits from all submissions if an export is requested for a form with an audit.

Which to me reads like there should be 1 file. But it exports multiple files?
