Would an automation based on the details in your child table(s) be sufficient? i.e. a Citation is marked as complete could use an automation to create the training record elsewhere that's linked to the Personnel record, or a certification is expiring in the next 4 weeks could create the training record for recertification.
If you truly want it based on the Personnel record's summary fields, you could also setup formula fields to contain the details to send to the training session record, then create a table-to-table import targeting the correct information, and ultimately have a scheduled automation to send those details once the correct condition is met.
