There is no easy way to copy the settings of one fixture to an other one, but what you can do is to use the load function.
Select the cue you want to edit and then click on the "load" button.
Selecting the already programmed fixture will display the current values for each parameter. Then just select the new fixture and click on the existing fader positions. It will set the new fixture to the same values than the previous ones.
I hope this will help you,
enjoy
