Create an add-appvclientpackage script script which creates the log on the local client. The sequenced application will be able to write into the local eventlog.
I used the same technique for a package I created in the past:
<MachineScripts>
<AddPackage>
<Path>"C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe"</Path>
<Arguments>-ExecutionPolicy RemoteSigned -WindowStyle hidden -Command New-EventLog -LogName "Application" -Source "custom_app_name"</Arguments>
<Wait Timeout="0" RollbackOnError="false" />
</AddPackage>
</MachineScripts>
The above script is an example to create a source inside the applicationlog. You could expand this to first create the Logname too.
