Auto Generate Cards from Sub Pages or Group Pages

[crippit]

I would like to automatically generate cards for each subpage, or each group. I don't see a way to do this, but it would save a huge amount of time. Here's how I would like to use it:

1. Generate a group of pages which support a theme
2. Create a main page for this group
3. Generate cards for each sub page as an index allowing people to quickly navigate to the page they want from that section

As far as I can tell there is no current way to do this?
