Network Discovery with a schedule

Can get a discovery job to get added and can rediscover manually, but if i add all the subnets to one discovery job (preferred, but with almost 4000 subnet ranges), i can edit it.  Think the number of subnets are too large and the request to edit times out.  Is there a way using rest/api (again prefer python) to set a discovery schedule on creation?

Thanks in advance to anybody that can help,
