As the SpecFlow Scenario Outlines documentation says:
the Gherkin syntax does not enforce that all example columns have the matching placeholder in the scenario outline, you can even introduce an arbitrary column in the example sets for better test method name readability
So you could introduce an arbitrary column into your "Examples" table to succinctly describe the intention of the test e.g.
Scenario Outline: Example
Given I am a user
When I enter <x> as an amount
Then the result should be <result>
Examples:
| example description | x | result |
| Example Description 1 | 3 | 3 |
| Example Description 2 | 1 | 1 |
This would result in the following test names:
Example_ExampleDescription1
Example_ExampleDescription2
