Universal Worklist

In our uwl.standard config file, the global attribute for date columns is set to date. I wanted this set to DateTime so I went into the actual file on the server and changed it.

I did this on our dev portal and would like to transport it now to our test portal. I tried exporting the uwl iview and role to our test portal, but the uwl.standard file remained unchanged.

So is there a better way to change <GlobalAttributes> or how can I transport the changes I've made to our test portal?
