Keep the mobile web chrome session open for the entire scenario outline

I am using scenario outline to eliminate duplicate

Example of scenario outline table:
| front_href | header_class |
| /nfl/ | .nfl |
| /mlb/ | .mlb |

For each scenario defined in the table creates a chrome session and kills the session at end of each. To speed up the mobile web testing is there any way to keep the chrome session alive for the entire scenario outline table execution?
