It is a similar process in FAM. you create CIP asset type with Zero depreciation. Then you add all your assets monthly; create a custom tag, say, "future asset", since you probably are going to have more than one, and they can be of different types unlike a compound asset where all assets must be of the same type. Or you can create sub-assets instead (but they all need to be individual standalone assets still) and sub-assets do not need to be of the same type. Then you convert each individual assets from CIP to the new asset type and start depreciating
