Change variable color of only one specific element

I want to prototype a table with a hover color per table line. To do this I had thought of creating a color variable for the fill and assigning it per line. Through the prototype I would then set an action on hover that changes the fill color to the hover color. However, this then happens immediately for each line.

Is it possible to set this so that it only happens per line? I considered making multiple variable modes but that might mean that I have to make 50 modes since a table can have 50 lines. This is why I am looking for an easier solution.

Hey there, are you able to share a screen recording or a copy of your file with me so I can have a better understanding?
