Question&Answer as Playlist AND ALL at once

I´m trying to do a question and answer with several Q&As, that

  1. you can hear all at once / Q&A + Q&A, until done.
    OR
  2. Just saying Back, Repeat, Next, like a playlist.
    =======
    I did for:
    1)---- (LIKE LOOP ARRAY, THAT GETS ELEMENT AND THEN NEXT ONE) —
    FLOW > intent / call subflow 1 / set variable+1 / SUBFLOW 1 — choices with IF conditional (integer variable equals to) ---- IT IS WORKING
    2)----- (LIKE ARRAY THAT PICKS A CHOSEN ELEMENT BASED ON CURRENT ELEMENT SELECTED) — Command 1 (Intent with Next) FLOW > set variable+1 / call same Subflow 1 ------ IT GIVES THE QUESTION BUT keeps running the Subflow 1 without audio. Any suggestions or better way to do it?

This is for Spanish-US / Mexican-US

Muchas gracias / Thanks a lot
