[logback-user] Job Logger configuration

OK so I am working on a custom job engine and I am trying to separate my
job logs from the main application logs as well as separating the logs
for each individual job run from each other.  My plan is to
use the sifting log appender to put the logs into a hierarchy on the
filesystem as the
 {job_group}/{job_name}/{instance_id}
I know I can pull multiple values out of the MDC for use in the pattern
layout but I am having trouble using them in the filename.
I am not sure my above approach will work for directory names but
according to the docs it should work at least for the filename.

My second question is how do I keep my job logs out of the main log?

Here is my current config:
<?xml version="1.0" encoding="UTF-8"?>

<configuration>

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by
default -->
    <encoder>
      <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level [%thread] %C:%L
%msg%n</pattern>
    </encoder>
  </appender>
  <appender name="jobLoggerAppender"
class="ch.qos.logback.classic.sift.SiftingAppender">
             <sift>
            <appender name="FILE-${jobId}"
class="ch.qos.logback.core.FileAppender">
                <file>${jobGroup}-${jobId}.log</file>
                <layout class="ch.qos.logback.classic.PatternLayout">
                    <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level
[%thread] %C:%L %msg%n</pattern>
                </layout>
            </appender>
        </sift>
    </appender>


  <logger name="com.lordofthejars.foo" level="INFO" additivity="false">
   <appender-ref ref="STDOUT" />
  </logger>

  <!-- Strictly speaking, the level attribute is not necessary since -->
  <!-- the level of the root level is set to DEBUG by default.       -->
  <root level="DEBUG">             <appender-ref ref="STDOUT" />

  </root>
  <logger name="jobLogger" level="debug">
      <appender-ref ref="jobLoggerAppender"/>
  </logger>
 </configuration>
