Ability to change the timeout threshold in the Confluence UI

Would like the ability to set the timeout threshold for a PDF Export. The following appears in the logs as a WARN

WARN [Long running task: PDF Space Export] [confluence.util.profiling.DefaultActivityMonitor] close Exceeded the threshold of 60000 ms: ActivitySnapshot{startTime=1425991343730, threadId=15781, threadName='Long running task: PDF Space Export', userId='', type='long-running-task', summary='PDF Space Export'} 

When the threshold is reached, the link to the PDF is not displayed. Instead, an error message regarding the threshold is displayed. This leads a user to believe the file is not created since a link is not displayed and only this error is shown. Looking in the <Confluence Home>/temp, the file is there. If the timeout was configurable in UI, we would not see confusion between this error appearing and the file actually being generated.
