Yes I hear ya… Based on your layout… Here’s what I would do. Don’t apply the interaction to the element itself, because it could get a little complicated doing this on each one. Instead apply interaction the “Button”.
Now what’s cool about IX2 is you can add interactions to “Combo Classes”, in IX1 you cannot. Depending if you want to be able to simplify your styles on each card? If you’re NOT going to have different button colors, styles, text, then simply add (1 or A) to each button class… All will have “Button A, Button B, etc”. On the tooltip do the same “Tooltip Background 1, Tooltip Background 2, etc”. This help to keep style format simple.
Next, I would suggest adding the “Initial” transition -100% in the styles panel to each tooltip, not in interactions, decreasing 1 more step.
With this format you can repeat the interaction without creating a new one each time… All you have to do is click the Button 1, and select affect different elements, then type tooltip background 1. Then click Button 2 repeat!
That would work for you layout
