The actual question should be "what do you want to do after storing them in separate properties"? I just wanted to understand the actual usage of the data which was saved for later use.
In earlier question, the solution was there how to extract the same. If you say what it should be used for, then everything can done in the same script without putting into separate properties test step.
And additional issue with the use of properties is that, at least in this case, there are no keys, only values are there and it is unnatural here to use properties. And in this context of your use case, the number of collected IDs may differ in size and no proper key name to access the right data.
Properties is preferred when we know the each of its key to access the right value.
