Thanks for your submission. We need more information about your request. Currently if you are creating a multi-table dataset, the goal is to create a single dataset for workbook consumers from multiple joined tables, files, etc. So there is a requirement as you say to join the tables in the dataset. If you would like to create a workbook/dashboard where you have multiple unjoined datasets, you can do so by adding these datasets in the Add Data section of the workbooks. This is where you can blend individual datasets or keep them unjoined and they are all available in the workbooks. If I'm misunderstanding you requirement, please provide more details. thanks.

@Rajakumar Burra — it is not clear why you need to add all the datasets here. One note is that when a dataset is in a workbook — the workbook assumes all the columns can be used together. So you are both managing datasets and also defining where joins work. It might be worth a call to learn more. Since the dataset is intended to make it clear how the data works together… maybe there is another solution to your challenge.
