Despite a bunch of pretty smart people chiming in here in this thread, what the OP is trying to do is NOT easy in Bubble, even though it should be.
We have no access to Things (objects) except by interaction with the database and in the OP’s case, parallel lists contained in multiple Custom States IS NOT viable (due to the set-like nature of Bubble lists). This is somewhat more manageable if using List Shifters instead of custom states, but it is still likely the OP will run into issues with null values in their parallel lists.
Because of all this, I did start on making a plugin specifically for use cases like this, but it’s not quite ready for prime time. (I posted a short video of this a while back.)
Here’s me talking about the null value problem: Live Bubbling with @keith! Talking about how Bubble handles empty list values, inconsistently. Also, updates to List Popper and Friends to work around that
That new plugin, dubbed “Karter” is still in development, but if the OP is interested, I could make them a beta tester and give them access to that plugin. (Private message me if interested.)
