Hello João,

From version 5.0 onwards, you can already convert local variables to output parameters. To do so, right click the variable and select "Cut" (or press Ctrl-X). Then, right-click the action and select "Paste As...". You'll be presented with several options, including output parameter.

After you paste the variable, the TrueChange engine will ensure all references to the variable are updated, so there's no extra work to be done!

Best of luck!
Rodrigo

Already Done.
