Dimensions (rename or wrap) in Freeform Table

I am working on a project in Workspace and have a freeform table.  I need to use mixed dimensions as I need to add up different levels of product dimensions.  However, when I add mixed dimensions, the level and the name are all in the label for the dimension, making them too long.  Is there a way to wrap them?

When I just filter in the top level dimension, the grand total at the top is too high as it includes everything in the dimension, even if I'm filtering to only one or two.

If I use mixed dimensions, it would look like this, the total units is correct, but the category names are cut off.

For the mixed dimensions, I'd either like to change the row labels (so just Pants, Dresses, T-Shirts, Socks) or wrap the names so the whole name is shown.  Is there any way to do either of those?
