Hi Dujie,
For restricting the data to a particular range,
select a microflow in the selectable tab of the drop-down and there you can use retrieve activity and then Set Range to Custom then, by defining the Offset and range, you can easily define the Range of the data.
Now, for the custom filter, you can follow a similar approach from the blog, I am providing the link below,
Let me know, if you face any issues,
Hope it helps!!
