Metasploit Framework

I wrote a meterpreter script to check alive status of a session and just run and idletime but it'd be nice to have it built in to the sessions command:

msf > sessions

Active sessions
===============

  Id  Type                   Information                      Connection
  --  ----                   -----------                      ----------
  1   meterpreter x86/win32  STEVESWIGETS\bob @ WORKSTATION1  192.168.100.150:443 -> 192.168.100.200:23856
  2   meterpreter x86/win32  STEVESWIGETS\steve @ DC1         192.168.100.150:443 -> 192.168.100.201:55189
