disable certain templates

[Johnny]

What im trying to do is call certain templates to be displayed in certain forums without using conditionals such as.

<if condition="$show and (in_array($forumid, array (X,Y)))"> $navbar </if>

but have something more like <if condition="$show[blah_template]"> $navbar </if>

(using $navbar template as an example)

im going to have too many forums and once i add more fourms just going back and adding a number to all the templates has thas the array conditionals that i dont want certain things to show in certain forums is just too much work.

so is their a way to do this as an option in admincp when editing or adding a new forum that gives an option if you want only enable/disable certain templates from showing in a particular fourm but not all
