Different shortcodes on different types of content

Hi Julio,

On a blog with 300 posts and 6 CTP with 120 posts (these posts are made by CTP for having an easier administration and for SEO reasons), I would have different widget of related posts in sidebar by using a different shortcode at each time :

1. On CTP posts : a shortcode like [bawmrp – tous les CTP idems – 4 posts – random display – random order – thumbnail mode]

2. On posts : [bawmrp – Same category posts – 4 posts – random display – random order – thumbnail mode – nofollow]

Do you think it’s possible ? How can I do that ?

Thanks for your answer,
Arnolito
