You can integrate one change by doing:
p4 integrate //depot/source/ ...@CLN1 ,CLN1 //depot/destination/...
And then you can integrate additional changes on top of this before submitting:
p4 integrate //depot/source/ ...@CLN2 ,CLN2 //depot/destination/... p4 integrate //depot/source/ ...@CLN3 ,CLN3 //depot/destination/...
It will be easy for you to write a script that iterates over the list of change numbers and executes the corresponding p4 integrate command for each of them.
