MSP 2010 - duplicating tasks and logic I have a schedule I am putting together for a repeating layout multi-floor building. Is there any easy way to copy the tasks and their predecessors and successors from say floor 2 and with minor renaming and editing and use them for floors 3-6? I've tried copying and pasting small batches of tasks, 6-8 at a time, and the logic within the task range updates with the new relative Task IDs, predecessors and successors outside of the copied task range stay the same, which is great but I am seeing other inconsistencies in the pasted task logic that has me wondering if I am missing something or maybe there is a better way to do this (short of using sub-projects for each floor). Any advice would be appreciated.

Create a summary task for floor one indenting all of the work underneath. Collapse the summary task - copy and paste. The links between the subtasks should be retained. What inconsistencies are you seeing?
