How to have “Splunk for Palo Alto Networks” read from the default index?

According to the setup documentation, the input for Splunk for Palo Alto Networks should write to the pan_logs index, however, I would prefer that it write to the default index. My hope is that making this change is as easy as updating the `pan_index` macro to point to the default index rather than pan_logs, but are there any other considerations?
