Use output of an executed script to populate a Custom Property field.

As an example, using Show Flash output shown below. If we could grab the "### byes free" and then shove the number displayed into a custom property, we could then use that to determine if the flash memory of the device can have additional files uploaded to it, This could be a serious time-saver. While this is what's pressing me to look for this capability, there are other commands where the output is not easily obtainable from SNMP polling or SNMP and syslog traps.
