Sure. Select Edit Table Calc for that calc on your sheet. Here is a screen shot where I do exactly what you are asking about:
You can drag the order of the dimensions so that they are ordered in the list in the order you want them evaluated. You may have to specify a "Restarting every" dimension, and sometimes you have to specify "At the level".
It's not easy to say what you specifically have to do. So often it depends on what is on the sheet and what you are actually looking to accomplish.
I tried modifying the table calculation but the options 'At the level' and 'Restarting every' are grayed out. I think it could be because the field with the table calculation is on the shelf.
