Can visibility be auto-assigned?

Issue Summary

I think this module is really snazzy! But I am having a little trouble figuring out how to make the "visibility" settings easier to deal with.

My use case is:
- a simple content type with fields "title" ,"body", and "sidebar".
- through the tpl I made it so the "sidebar" displays if $node->nodesinblock, otherwise the "title" and "body" display.

That means that the main content (let's say a recipe) and the sidebar (let's say a list of ingredients) are connected on the same edit page, but the sidebar content displays in the sidebar. Awesome! That is exactly what I want.

However! When a user creates a new recipe, they have to know/understand enough to set the visibility to "node/345" or whatever node they're working on [it also means they can't set visibility until the node is saved and has been assigned a path &/or nid].

At least, that's how it's set up right now. Is it possible to set it up so that the block auto-displays only on its own node, without the user having to set it specifically? (It seems like the settings can handle this but I read through the readme.txt and couldn't figure it out.)

Thanks!
