Easy way to copy over calculated fields to another dataset

I have a dataset in which I created about 10 calculated fields. I
often use this dataset for other reports. How can I copy over those
fields to the dataset I create in my other reports quickly?Hi.
Edit the code (RDL) of the report, look for the dataset fields, copy
and paste them onto the code of the new report.
