Multiple template for a single post

Hi Guys,
Is it possible to assign multiple template for a post depending on the categories it has been assigned to? I mean, I have a post ‘Post A’ and two different categories ‘CatA’ and ‘CatB’. The ‘PostA’ has been assigned to both of the above categories. Actually what I need is, when I click ‘PostA’ from ‘CatA’ it should be in one layout and when I click from ‘CatB’ it should be in another layout. How it can be done? Please help guyz.
Thanks in advance.

Hakkim.
