You would need an external script that calls the Export Job and then the Import Job.

'External" Script?  Do you mean a User-Defined script I write within Sage Custom Office or Button script?  If so, can you provide an example of the syntax for that script?

There is a KB article on running VI jobs from a batch file.

Beware that the batch file does not wait for a job to finish before starting the next command (in the batch file).  You have to handle that yourself.

One way to chain is to have Perform logic for the first job (upon completion) which starts a batch file triggering the second job.

I thought you could chain an import job to an export job with a trick, unless it doesn't work anymore in recent versions. Let's say you're in Import Job Maint and want to chain an export job. In the Chain To field do NOT click the lookup. Instead type in the exact name of the export job in upper-case. Click Accept and test it. That should do it.
