Add prefix to custom action variable

Another great feature would be able to name the tool in a way that could be used as the prefix in the variable for when we have more than one custom action. I know the variable gets replaced after the next run, but when trying to reference all of the variables with instructions in the prompt. For example if we have 5 custom actions in one assistant, we may reference <results.data.id> multiple times. I'm thinking if we could have a name as a prefix like <book.results.data.id> that would be great.
