I am working on a custom job board for a client that wants to deploy this job board on a multi-site network. Here is my problem, I need to store certain jobs in a table that would be accessible to all sites in the network (e.g. a nationwide listing) instead of just locally (e.g. local listing).
My question: can data from a custom post type be stored in a custom table?
Edit: Perhaps more clarification is needed. My client has a multi-site network job board. There are job boards for specific regions (e.g. San Diego, Austin, Denver, etc.). Right now, a user posts a job for Denver on the Denver site but if he has a job he wants to advertise nationwide, he would have to post the job on all sites in the network. We want to create a custom post type for jobs that gives the user the opportunity to select a nationwide category and upon saving the job, have it show up on all the sites in the network. The one way we could see making this work would be to have a job tagged as 'nationwide" save its data in a separate table outside the typical wp_1_posts table so that we could query that table for nationwide jobs and list them on ALL the sites in the network automatically as a part of the theme.
