Twitch > Points Reward Redeem : Store infos about «Twitch» conditional triggered to use them

[KarhellTwitch]

To explain by a use case:
There is a points reward redeem to get a VIP available 1 time every week (cooldown on the request) if the next week an other viewer takes it, we want to /unvip the previous one to /vip the new one (and replace the username stored with the new one).
Actualy there isn't (or i haven't find it) a way to grab the username from the triggered «Twitch» conditional to write it in a file or in a variable (by writing something like ${redeem.username})

Idea: In the «Twitch» conditional block a way to store in variables the infos from the event who triggered the conditional block and then a way to use these variables in the File content/Send chat message/... with a keyword like ${variableName}

Sorry if I am misunderstanding your request but can you not do something like this to grab the user name of the person which redeemed the VIP reward?
