SNMP Trap External Alerting

Since the SNMP Trap external Alerting has a limit of 1024 bytes as stated below:

"With SNMP trap delivery your collector will send an SNMP trap to a SNMP trap server for each alert triggered on the group(s) specified.  Note that SNMP traps must be less than 1024 bytes, so the message may be truncated"

Can the size be increased so the message does not get truncated?

Thanks
