which methods do we have to bulk-import data into the wpjobmanager!?

hello dear wp-experts,

which methods do we have to bulk-import data into the wpjobmanager!?

does the wp-job-manager offer some solutions or methods to do so – or

do we do this in the backend – the database or do we need to use this awesome third party plugin!?

can any body tell me how the data look like in default – the data of the Job entry …

i eagerly want to know this – and if i know it – i can do imports on the db-backend
