logback ThresholdFilter how todo the opposite - logback

Question

I need a filter that only passes through everything info and LESS instead of info and more. I have seen this done somewhere before in logback. My full xml is here and I want info and less to go to stdout (without writing a filter as I know that was possible somehow)...
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>info</level>
</filter>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date{ISO8601} %X{sessionid}-%X{user} %caller{1} %-4level: %message%n</pattern>
</layout>
</appender>
<appender name="STDERR" class="ch.qos.logback.core.ConsoleAppender">
<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
<level>warn</level>
</filter>
<layout class="ch.qos.logback.classic.PatternLayout">
<pattern>%date{ISO8601} %X{sessionid}-%X{user} %caller{1} %-4level: %message%n</pattern>
</layout>
<target>System.err</target>
</appender>
