"Is there a way to do a similar table at the feature level that will cause the entire feature to be executed for each row in the table?"
No, Specflow (and indeed the Gherkin language) doesn't have a concept of a "Feature Outline" i.e. a way of specifying a collection of features which should be run in their entirety.
You could possibly achiever what you are looking for by making use of Specflow tags to tag related scenarios. You could then use your test runner to trigger the testing of all the scenarios with that tag e.g.
@related
Scenario: A
Given ...etc...
@related
Scenario: B
Given ...etc.
