Send only part of trap details (${MESSAGE} variable) in e-mail from trap viewer

Hello!

I'd like to be able to send an e-mail alert from trap viewer that only contains one line from the trap details. It appears that the entire trap details block is contained in one variable ${MESSAGE}. Is there a way to isolate one line?

Instead of sending this:

     Received Time:6/11/2014 4:24:50 PM

Source:10.1.2.3(bigip2-self-10-1-2-0-vip)

Community:snmpcommunity

     Variable Bindings

bigipNotifyObjMsg:= SNMP_TRAP: Virtual /Common/dns-int-vip has become unavailable

snmpTrapOID:= F5-BIGIP-COMMON-MIB:bigipLtmVsUnavail (1.3.6.1.4.1.3375.2.4.0.136)

sysUpTime:= 50 days 3 hours 43 minutes 36.65 seconds (433341665)

experimental.1057.1.0:= 10.1.2.3

snmpTrapEnterprise:= F5-BIGIP-COMMON-MIB:bigipNotification (1.3.6.1.4.1.3375.2.4)

I want to just send this:

bigipNotifyObjMsg:= SNMP_TRAP: Virtual /Common/dns-int-vip has become unavailable

Is that possible?
