Hi Dave. I would like to make the change. May I find out how to do this?

Look at the combined blocks as they exist now and understand how they work. That's step one.

Note down the <trial> elements that have the same correct response key in each combined block.

Note down how many trials there are of each type.

Note, too, that combined blocks always alternate between attribute and target trials.

Your easiest option is to simply spell out a fixed trial sequence that satisfiies your added constraint.

Otherwise you need to come up with an algorithm that produces random trial sequences that satisfy all the properties above and implement it. This is not trivial.

Thanks Dave. I have noted on the number of trials for each combined blocks. It would be ideal to come up with a script to produce random trial sequence that limit not more than 4 times the same response key in each combined task. 

That is what you should work on then. What you have on your hands there is a constraint satisfaction problem (cf. https://forums.millisecond.com/Topic6419.aspx ), so be prepared to spend some time on this.

Thanks for the information. Is there a starting script or section where I can work on? I have no background on computer science/scripts so it will be great to get some advice from you.

Hi there, may I find out if it is possible to limit same-key correct responses for IAT in combined tasks to less than four consecutive times? 

The short answer is no, there is no easy or straightforward way to do this.

The long answer is anything is possible if you're willing to make deep and major changes to the code.
