If it were me I would try the following.
Install a test copy of WD so you now have 2 copies. The new copy will have a new ini file. You can then get the data from the original copy and customize as you see fit. There is an FAQ on how to do this here http://discourse.weather-watch.com/t/10889
There are some client/server issues that you may encounter depending upon how you choose to get your data. Doing a search on terms like client server and then weeding thru the responses will show you how to set up such a system.
hope this helps
