Randomize embedded data with no repetition

Hi all, I want to randomly present 20 pictures, which are randomly paired with 20 sentences. The order for both pictures and sentences are expected to be randomized.

However, if I use loop and merge, the pairing between pictures and sentences will be fixed; if I use embedded data function, The pictures and photos will appear randomly in each iritation so that the same picture/ photo will show up multiple times.

Is there any way I can achieve this? Or any hint on using Javascript to achieve this?

Thank you so much in advance!!!

    Yes, using java script you can create two arrays, then shuffle them and set them to an embedded data.

    It a bit long to program, but you can do this with the branching logic and randomizer in the survey flow. I'd group all this in a single group block so that it is easy to copy and repeat between each iteration.

    Basically you need to create an indicator that a value has been selected by the randomizer, then suppress that option if it was previously selected. You can do this by setting an embedded data indicator a block when the choice is selected and then using branching logic to hide that block when the indicator has been set.

    LOL - Having re-written the above paragraph a dozen times, I realize that this is a lot easier to show then to type. Attached is a simple demo of this where it goes through the process 3 times. It wouldn't be that much work to program it to 20.
