Datalogger IP & Davis WeatherLink website question

I understand from the IP logger manual, that the datalogger uploads data to the Davis website as soon as it is powered up and connected to the internet.

Does the Davis website allow for user deletion or removal of any test data that may get sent before the weather station is ready to start recording accurate weather data? Or is it better to not set up the datalogger only after the AWS installation is complete?

Thanks
