Is there a conditional for this?
 

I want to know if there's a conditional for paid subscriptions...

Example of what I'm looking for:
<if condition="subscription[1]">

With the '1' being the ID of the subscription, remember I'm not talking about being subscribed to forums - rather paid subscriptions.

Also I know there's the conditional '<if condition="$show['subscriptions']">', I'm looking for one to point at a specific subscription, not all.

Thanks for any help
