How to change ringtones on expansion module lines?

[mhardyuop]

I have 7962's with 7915 expansion modules.  Is there a way to change the ringtones for the  lines on the expansion module?

I do not see them listed as options in the settings to change the ringtone for the lines.  I only see the lines on the actual phone listed.

This is a cluster running 6.1.4

Thank you
