Okey, in the end it finally work, I rewrote the code for the flyout action, so I could call it specifically for any "Flyout hotspot". Using something like flyout(spotname) it activates the flyout of the desired hotspot, inside the function I used %1 as a reference for the action. My trouble is that I was using a function code copied from the "Krpano viewer examples" which works from inside the <hotspot> tag, because it's activated from the "onclick" event, it refers all the hotspot parameters to the ones specified inside the specific flyout hotspot tag, which wouldn't work activated from another hotspot. Anyway, thank you Zephyr for that answer, I really like the collaboration ambience here in krpano forum, that's really useful for beginners like myself.
Ohh, by the way, the final animation flyout looks pretty cool for my taste, when the tour is done I'll post it for critics. Regards!
