Ok – I think I’ve got it.
Short answer is – you can’t.
The most fundamental idea of eaDocX is that you define how a ‘thing’ gets printed, then wherever that ‘thing’ appears, it gets printed in the same way.
What I think you’re asking for is for, in one part of the document, Package things to print in a table, then later in the same section, for them to print Inline, with ll their children & child diagrams.
The only exception to this rule is for Element Reports, where we allow the formatting of the results to be different. This could give yo a bit of what you want – a list of the Child packages – but in a separate section.

We’ve had a long discussion about this, and decided that what you’re asking for is so different from the way that eaDocX works, at the very lowest level, that we can’t fix this for you.
