You can do this, absolutely. We are FUSE, after all, and working with multiple services is our thing.
Pushing FUSE Trends™ data to multiple Google Analytics accounts is supported. By default, with our Enterprise and Standard instances, one Google Analytics account is included; others may be added for a modest fee (please consult with FUSE support, your FUSE account handler, or see the Additional FUSE Trends™ Accounts section of FUSE's pricing calculator).
