Save multiple posts at once

Hi there,

I'm trying to build a calendar where users can reserve slots. Their choices get defined by other metaboxes, and Meta Box has so far performed admirably in tying everything together.

I'm going to get lots of data points with clearly defined structure, all of which need to be queried quickly, which leads me to think of a custom table, and in fact I've set one up, and it's working with frontend submission.

The tricky part is that I want to make adding events easy, and I'd like to facilitate adding more than one event at a time.

Your approach for creating cloneable groups of data is MB Group. I like it, and putting together a group seems straightforward. But it gets stored as serialized data and isn't very accessible after the fact. So maybe not the best for custom tables.

Ideally, I want functionality similar to cloning field groups, while saving data as new rows in a custom table (i.e., a new post, yeah?)

How would you approach this issue?

Thanks!
