Customizing Request's contents - Transfer them to a new request

Question

I have created one huge transport request (customizing) with many IMG actitvities or configuration on customizing views.
and it looks some thing like this:
ERSK900262 050   Dneelima     Customizing HR
              ERSK900263   Dneelima     Customizing Task
                  Table Contents
                  View Maintenance: Data
                  IMG Activity  Define Savings Plan General D
                  IMG Activity  Define Miscellaneous Plan 
                  IMG Activity  Define Administrative Parameters
                  IMG Activity  Define Miscellaneous Plan General 
                  IMG Activity  Change Screen Modifications
                  IMG Activity  Set Up ESS Parameters
And the list goes on.
Question: How can take 2 IMG activities out of the list delete it from this request and add it to anew request.
The idea is now to assign these activities to different transports and release them in different order.
Any inputs ?

Thanks for the reply.
But I am not sure if I am following correctly. I tried to assign, split, merge etc, But it works if you have different tasks within a transport.  In my case I have all those "IMG activites" within one task.
I am not able to assign those individual "IMG activity" to another transport request ?
Please suggest if this is possible at all or am I missing something here ?
Thanks again !
