Feature request: recursive function of hidden on pages

[h3nn3s]

Hi,

we are sending Newsletters out of our TYPO3 with direct_mail.
For this, we set up a subtree under root page for newsletter configuration and handling new pages.

Currently we have to add every new page to $siteConfiguration['klaro_hidden_on_pages'].
It would be really helpful, if there would be a flag to enable recursion on the given page ids.

Any change to get in such a feature?
How an implementation could look alike? Maybe a new field $siteConfiguration['klaro_hidden_on_pages_recursive'] would fit better in terms of BC instead of a flag which would then work recursivly on every pid.

Best Regards
Henrik
