Cumulus Support

So, the laptop I have my station connected to disconnected from the Internet a few days ago. Because I only go to the location once a week, I couldn't fix it right away. All the data from these days is in Cumulus and saved, and I'm wondering if it is possible to force a catch-up of this data to Wunderground, without having to use the datalogger, but instead the data that's already stored in the files.

Thanks!

I have an Excel spreadsheet that can do it if you are interested?
