Is it possible to remove only one label using Butler?

[Salesianos Estoril]

Hi. I´m trying to make a rule (using butler) that allows me to move a card from a list called "To Do" to another named "Doing" changing automatically just one label of 3 that I have in the card... I only find the option to change all the labels instead of only one...

Unless I'm missing something, it looks like it's possible?


Here's what the action looks like:

Could you achieve what you need by adding one label and removing another label in your rule? Something like: 

when a card in list "To Do" is moved into list "Doing", add the green label to the card, remove the blue label from the card
