how to run multiple test cases in same excel

how to run mutiple test cases in the same excel?

 

Now we have longer test script with mutiple lines and finding it hard to maintain.Planning to break down to small test cases but keep it on the same excel sheet on the same tab.

In test complete how will we run each test cases if its in the same excel?

 

 

Team dont want to keep it in the different excels as it becomes difficult for them to search.
