How to merge two scripts of the same URL in QTP 9.5

[Rangi]

Hi all ,
I have some test cases which has common steps..
e.g. Test Case 1: Steps a,b,c,d,e,f,g,h
Test Case 2: Steps a,b,c,d,i,j,k,l.. etc.

So i need to record and create a common script for the common set of steps (e.g. a,b,c,d) and then have separate scripts for the other steps in each test case (e.g. 1. e,f,g,h 2. i,j,k,l).

My plan is to create a common script and then create separate scripts. And then merge the common script and the other scripts as necessary.
so the Scripts for the test cases will look like this,
Test Case 1: Common Script + Script for steps e,f,g,h
Test Case 2: Common Script + Script for steps i,j,k,l

Is there a possibility to do this? If so please let me know.

NOTE: I am using QTP 9.5

Thank you
