I note that you define `_hash()` to create a `hash_id` from non-id column values in a table [here](https://github.com/simonw/sqlite-utils/blob/8f386a0d300d1b1c76132bb75972b755049fb742/sqlite_utils/db.py#L2996).

It would be useful to be able to call a complementary function to generate a corresponding `_id` from a subset of specified columns when adding items to another table, eg to support the creation of foreign keys.

Or is there a better pattern for doing that?",140912432,issue,,,"{""url"": ""https://api.github.com/repos/simonw/sqlite-utils/issues/343/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,completed
