Couple things.... - you're asking for a feature to be able to skip saving data to the db... - yet you want to check your new installation works... - which 'requires' saving data to the db so you can check that - in other words - what you're asking for would prevent you doing what you want to do (huh?) - and secondly missing a few readings isn't the end of the world worst case
If you have the official Davis datalogger that stores up to a week or so of readings from your sensors as long as the console is powered up. Weewx will gracefully catch up to any records the datalogger has that the db doesn't (yet) have stored and you won't miss any readings. If you have a third party logger with no such storage, your mileage may vary.
