Triggering Multitail to start tailing when 'string' arrives

I am using multitail to monitor a group of logs. I have been seeking a solution in the multitail options to start tailing a log only after the arrival of a matched string. I see plenty of capability in multitail to use -e and/or -ev to include/exclude rows that match the regex criteria, but not so much using a "trigger" to start tailing. I am currently targeting 4-6 logs, separate panes, not merged, where the criteria above would be applied to each log entry ( -i ). I would appreciate thoughts on an approach.
