Specify separate tables for each Celery task

Say I have several Celery tasks like this, dumping their results to an SQLite database every minute:

CELERYBEAT_SCHEDULE = {
'do_task_add': {
    'task': 'tasks.add',
    'schedule': crontab(),
    },

'do_task_multiply': {
    'task': 'tasks.multiply',
    'schedule': crontab(),
    },
}

And this is my database configuration:

BROKER_URL = 'sqla+sqlite:///database.db'
CELERY_RESULT_BACKEND = "db+sqlite:///database.db"
CELERY_RESULT_DBURI = 'db+sqlite:///database.db'

All results get added to the default table celery_taskmeta. Is it possible to define your own tables for each specific task? Having many tasks going on at the same time, it can be hard to distinguish them when they share table.
