Since we have dm_ptype() already.

If I have a named list of tables, or a dm of tables without constraints, or without all the constraints I need, I might use dm_cast(incomplete_dm, my_dm_ptype) and it would apply the missing constraints if applicable, or fail.

Is there a simple way to do such thing with our current tools ?

The idea I have is to edit the structure of the ptype or template dm to change the tables, but it means I keep the same uuid and I'm not sure if it's a problem or not. In any case this would be using implementation details so not good practice.

How is this related to dm_decompose() and dm_get_tables(keyed = TRUE) ?
