Combining targets

OK so I usually form my sequences exclusively using the framing& mosaic wizard so I now have a list of individual target sequences.
My question is: is it possible to combine targets into another sequence??
For example say I have 2 target sequences 1 & 2 but I want to image say 2hrs on target 1 before then imaging target 2.
can I create a new sequence with both targets in it from the previous sequence (F&M wizard) data or would I have to start from scratch?
Think I know what the answer will be but want to check just in case
