Nlog Logrotation, keep 7 days of logfiles than archive it every sunday

Question

Is there a way to create a log rotation with NLOG that records a log for each day for seven days and then archives them after the seven days?

this is my current target with this i :

<target xsi:type="File"
            name="error"
            layout="${longdate} ${uppercase:${level}}: - ${message}"
            fileName="${basedir}/logs/Error.log"
            archiveFileName="${basedir}/logs/archive/Error{#}.zip"
            archiveNumbering="Rolling"
            enableArchiveFileCompression="true"
            archiveEvery="Sunday"
            archiveAboveSize="10000000"
            maxArchiveDays ="28"
            archiveDateFormat="yyyy-MM-dd"
            concurrentWrites="false"/>

NLog likes to have single static file, but maybe this is possible:

<target xsi:type="File"
            name="error"
            layout="${longdate} ${uppercase:${level}}: - ${message}"
            fileName="${basedir}/logs/Error.${date:format=ddd}.log"
            archiveFileName="${basedir}/logs/archive/Error.{#}.zip"
            archiveDateFormat="yyyy-MM-dd"
            archiveNumbering="DateAndSequence"
            archiveEvery="Day"
            enableArchiveFileCompression="true"
            archiveAboveSize="10000000"
            maxArchiveDays ="28"
            concurrentWrites="false"/>

Then ${basedir}/logs/-folder will grow to have 7 files:

Error.Mon.log
Error.Tue.log
Error.Wed.log
Error.Thu.log
Error.Fri.log
Error.Sat.log
Error.Sun.log

And when "rolling" to next file that already exists (ex. Error.Mon.log), then the old file will be moved to ${basedir}/logs/archive/-folder and renamed to Error.yyyy-MM-dd.log (Using timestamp of when the old file was created)
