[Snapshot Pro] Snapshot Backup Execution Time

The snapshot backup is complaining that my max-execution time is set to 30 seconds and it wants me to change it in my PHP settings which would require and edit to the settings ini and affect the whole site. There is a PHP function called set_time_limit() that can be used to temporarily change this value for the executing script. Is that not part of this plugin, or is it not detecting that it can do that?
