Qualtrics Reaction Time Engine (QRTEngine) is an extension to Qualtrics which allows researchers, but generally any who are interested, to easily build behavioural online experiments.
Currently, there is no way to dynamically get all Loop & Merge data that has been defined for a trial. This makes the set-up process a bit more cumbersome, again, since the user of the Engine has to manually store the information contained in each column, sadly.
Qualtrics Support has issued a few feature requests regarding this functionality, specifically being able to name the Loop & Merge fields (so semantic context is not lost while using them) and an set/getEmbeddedData like API for JS retrieval of LM fields.
Currently frozen, waiting for these issues to be implemented.
