How to name embedded data fields using loop & merge values

I've got a survey where I'm using loop & merge to loop through a few hundred images with links (participants see a random subset).
I am using javascript to record whether they click on the link provided, and it records an embedded data field with a 0 or a 1, like this:
Qualtrics.SurveyEngine.addOnload(function() {
  $('link').on('click', function(name, event) {
    Qualtrics.SurveyEngine.setEmbeddedData("clicked${lm://CurrentLoopNumber}", '1')

I know that I need to have an embedded data field created in my survey flow, so I can create a few hundred embedded data fields.
The problem is that I want to name the embedded data fields with the information from the loop & merge fields (this would contain the image ID, for example).
I don't really want to have to create several hundred embedded data fields by hand, one with each image id.
Is there an easy way to simply pipe in the Field/1 values from loop & merge?
