Replace Conditionals with Variables?

[grey_goose]

I've got a ton of conditionals in my postbit, and am wondering if there's a more elegant way to do what I want.

The following swaps backgrounds for usergroups:

<vb:if condition="is_member_of($post, 11)"><div class="userinfoctl">
<vb:else />
<vb:if condition="is_member_of($post, 36)"><div class="userinfogse">
<vb:else />
<vb:if condition="is_member_of($post, 46)"><div class="userinfohtv">
<vb:else />
<vb:if condition="is_member_of($post, 12)"><div class="userinfomta">
<vb:else />
<vb:if condition="is_member_of($post, 47)"><div class="userinfoptc">
<vb:else />
<vb:if condition="is_member_of($post, 14)"><div class="userinfowod">
<vb:else />
<vb:if condition="is_member_of($post, 13)"><div class="userinfo2">
<vb:else />
<vb:if condition="is_member_of($post, 10)"><div class="userinfowtf">
<vb:else />
<div class="userinfo">
</vb:if>
</vb:if>
</vb:if>
</vb:if>
</vb:if>
</vb:if>
</vb:if>
</vb:if>

Can I get rid of the majority of this with something like:

<div class="{vb:raw is_member_of}background">

...and then just rename my classes "46background", "12background", etc ?
