Hello!
Currently not, we're sorry (you need to send a kill signal to Hummingbird and restart it with a new profile, which is not exactly what you ask for), but this feature will be available in the frontend+daemon solution. Hummingbird will be maintained as a stand alone binary and will also evolve in to a new software. The daemon is already in advanced development stage and initially we will release it together with a CLI frontend. Immediately after that, development of a GUI for the daemon, based on Qt, will begin.
Kind regards
