XF 2.2 How to create a custom variables? That I can re-use on templates / template mod / advertising?

How to create several custom variables that I can re-use on templates / template mod / advertising?
All those variables will just store NODE IDs.

Instead of manually adding this kind of conditional:
<xf:if is="in_array($__globals.forum.node_id,['1','2','3','4','5'])">
<xf:if is="!in_array($__globals.forum.node_id,['1','2','3','4','5'])">

I need to create some custom conditional out of it, like:
<xf:if is="$private_forums">
<xf:if is="$public_forums">
<xf:if is="$optional_forums">

So it's easier for me to alter node ID for each variable on one place.
Thanks a lot.

You are most certainly doing smth. wrong as the condition should even work with XF 2.0.

Your HTML comment serms to output a string that looks like an array, if it was a array it should output snth. like

<!-- Node: 113 ; Config.php list: Array -->

Triple check your config.php code or post the snippet here.
