If you want to be able to later reuse the particular combination of report settings you entered into the input form and used to generate a report, you have a couple options:
  1. You can bookmark the generated report. The report page contains an embedded copy of the settings used to generate it. This way, when you access the bookmark in the future, the report settings will be used again to generate a new report (updated as appropriate with new log information).

    This option is quick and easy, but it won't let you modify the settings.

  2. If you want a permanent modified version of the input form, preloaded with settings of your choice, you'll need to do a little more work. First, return to the input form. Make sure the settings are as you want them. Click the debug/save checkbox next to the report generation button at the bottom of the input form. Click the report generation button. Instead of getting the usual report, you'll get the underlying commands used to generate the report. Cut and paste these commands into an analog config file and modify the index.html page to add that to the <select name=CONFIGFILE> tag.
