Publish old results

It works perfect, but if i need to publish some old versions of dashboards or old results (from last week) i cant do that.
The logShark ask me to add log file. Could you explane how it works if it's possible.

dotnet /app/LogShark.dll --publishworkbooks --url http://localhost/ --site test
The LogSetLocation field is required.
Specify --help for a list of available options and commands.

Could i open some feature request for adding that functionality?

If you explain a bit more, I can try to figure out what is the requirement here.
Are you saying that you want to publish a custom workbook or you want to combine two logsets in the existing workbooks?
