Hi @lmckeega1! Thanks for sharing your use case.
It is possible to manually add assets from Lansweeper Cloud to start attaching financial data. However, as a general rule, when our scanner detects those assets, unfortunately, it will identify them as new assets and add new items to the Inventory, not merging them with the manually created ones (since it does not know that it is the same asset).
There is an exception to this rule, which will only affect Windows-type assets. If the newly discovered asset shares a MAC address with the manually created one, Lasnweeper will merge both assets keeping the financial data (or any other data) manually entered.
Regarding the asset ID change, as long as serial/mac/model is filled in, the ID stays the same, and the manually entered data is kept. If this were not the case, a second asset would be created due to the detection of the new domain (with a new ID), and the manually entered data would be kept attached to the first asset (which would not be deleted because it contains manually entered information).
I hope my explanation was clear enough. If not, please let me know š
