I am using P6. i have two WBS created with one Submittal of Material list and the next submission of PO with same activities. Now i want to link each activity in Submission of PO wbs to Each subsequent activity in Submittal of material list. I have many activites so linking each is very time comsuming. Is there any way to do this like "link all activites" etc... (Again remember activities are in different WBS)
