I understand the use that you’re after with this feature. In its current form, when you’re setting up the render conditions, the row that will be evaluated in the Source Model will either be the first row of the model, or the row ‘in context’ if there is one. There are several other “Source Type” options available that may be useful for you, including “Snippet returns true,” and I would also encourage you to submit a post to the community as an “Idea” describing how you’d like to be able to use the conditional rendering.
