Explicitly set RefId in the query builder

Hey does someone know if there’s a way to explicitly set a query’s refId? For now you can do it by modifying the json file but I would like to do it in the query builder

If you’re wondering, I’m talking about this:
refId

Here it’s somehow undefined because it seems that when “name” is defined, “refId” is not, otherwise it takes the query’s letter;

Thanks
