Cannot create hierarchical property assets using "Add asset" sub page of RE_LS_P_ADD_XFER

Our organization manages property assets (owned and leased) with a common hierarchy:

- Level 1 (Site)

- Level 2 (Building)

- Level 3 (Floor)

Most of our rentals are only at the floor level, but we store some of our data at the other levels for consistency of reporting. We would like to use the Add asset sub page, as it allows us to tie creation of the asset to execution of the lease, but it would not complete the job, as it would require us to go back and create the additional levels in AM. Is this a piece of functionality that exists and we have missed how to use correctly, or is this something that should be an idea for a future
