Import table structure/columns in sub-tables

I'd like to ask for table structure replication for subcollections/subtables.

Currently, each subtable in a record has to be initialized manually, since it's impossible to import table structure from other places. But it would be great if this schema was synced automatically. Say, the same table structure for all subtables in a particular table.
