Open app in a different desktop
I have tried that in Yosemite but not in Sierra, but you could try to disable the desktop autoswitching.

Open terminal and enter:

defaults write com.apple.dock workspaces-auto-swoosh -bool NO


the restart the dock with

killall Dock


To revert to the default setting type

defaults write com.apple.dock workspaces-auto-swoosh -bool YES
killall Dock
