Infomaker Custom Tab - Master/Child relationship

Is it possible to design an Infomaker Custom Tab that will represent a master/child relationship of data?

I have a new screen to develop that will hold multiple constituent IDs as repeatable entries within a single main screen, and would need to save back the child constituent IDs into a separate table with a foreign key relationship back to the main data table.

The TR_CUSTOM_TAB settings only allow for a simple Update Table entry that implies it can only save back to the main data table, and would not update the child entries as well.

Or can this be achieved using a web page application inserted as the custom tab? The documentation says that web pages cannot update data. Is this so even if the web page has it's own Save button?

I may be thinking about all of this from the wrong perspective.

All help appreciated!
