Transfer Activity Settings (data screens, power modes, etc.)

Hi. 

Is it possible to transfer Activity settings from one Instinct to another?  There are many posts on this, and I've seen the Garmin support page, which states that "settings" can be transferred but is not specific about exactly which settings will be transferred by copying the settings.fit file across.  I've created a couple of power settings for specific activities and I've got custom data field settings for all the activities I use;  will these settings be transferred across in the settings.fit file?  If not, is there a way to do this other than sitting with the devices side-by-side for a couple of hours and setting up the new watch like the old one.

Thanks in advance for any help.
