Hi,
yes you can do this.
Therefore you have to modify the XML source.
Create a field,select it in the design view and go to the XML source view.
You will see it's structure as a set of XML tags.
By default Designer removes all tags, which aren't used for the layout, so the needed <border> tags are missing.
Add them manually.
As there are 4 edges in a field, and you only need to hide the left one, you have the set up all four edges individually.
The left edge is the fourth, which needs to be hidden.
You also can use my macro, to modify the layout of fields.
