There isn't a buffer as you are asking but it is pretty easy to populate a
variant array of the columns you want the values for.

MyVarient := MyDataset[ 'COL1;COL2;COL3' ];

You can put whatever columns in here you want and store the values aside.
Then you can assign them back easily:

MyDataset[ 'COL1;COL2;COL3' ] := MyVarient;
