I don't think it would be a good idea, It is logic right now, it is like having the same set of event (not only actions) placed one after another:

Consider this, the entire purpose of a loop is to execute a set of events over and over and over and over until it has done it enough times or stopped by some event. Logic, and the standard way of thinking in most programming languages, I believe, would dictate that loops, intuitively, are simply repeated actions.
If I want to rotate a wheel 90 degrees clockwise, then I would simply rotate a wheel 90 degrees clockwise. You don't need a loop for that. If I want to rotate a wheel 90 times, one degree at a time clockwise, then I'd use a loop. I'd only put a command in the loop one time at one degree and then the loop would execute that 90 times. So, whatever I put in the loop code block, intuitively and logically, I want that to run for as many times as the loop runs. Whatever happens behind the scenes is all up to the creators of Construct. They can choose to program the Wait command any way they want, but I believe that the more intuitive you make something, the better the product is and the happier the users are!
Right now, I believe most new users of Construct, especially those who program in other languages, would find it a headache to wonder why their instructions in a loop execute "all at once". Certainly they can look into the matter spending a few hours searching the manual, looking through many tutorials which aren't cross referenced and even wait for someone to answer "that same question again" on the forums, but that means the user interface isn't as intuitive as it could be. There is room for improvement.
For me, I read the manual many times looking for the answer but couldn't spot it. I was looking through the tutorials, but I didn't think the problem was the Wait command, I thought I was structuring my loops the wrong way! I was doing all kinds of searches on LOOP STRUCTURE! I thought I had the conditions and sub events with my actions in the wrong place!
