How do I add additional community strings in HPOV

[harrisa9494]

How do I add additional community strings to the IP networks in HP Open View NNM. Currently I have 1 community string assigned to all the IP networks in SNMP configeration. Through the SNMP configuration, it does not allow me to add an additional community string to an IP wildcard (e.g, 170.95.*.*). While investigating this issue I read where it can be configure within the netmon.cmstr file.
