It's now possible to filter by multiple slugs including the option to define wildcards with the delivery and management api.

The following two filters have been added:

by_slugs

Get stories by comma separated full_slug. You can also specify wildcards with *. Examples: by_slugs=authors/john,authors/max, by_slugs=authors/*,articles/*

excluding_slugs

Exclude stories specifying comma separated values of full_slug. You can also specify wildcards with *. Examples: excluding_slugs=authors/john,authors/max, excluding_slugs=authors/*
