Just got my Sansa Clip today...why can't I move podcasts from my laptop to my Sansa Clip?

I find it convenient to separate my music which (administered and synched  by Win Media Player) which I seldom erase, from my podcasts which are generally erased after listening.

 I do this by using the external uSD card that is plugged into the Clip+ for storing my podcasts.  I simply plug Clip+ into my PC and open its  "external memory location, and then copy the downloaded podcasts into the Clip+  Podcast folder.  Doesn’t matter if podcasts are all in a single folder, as Clip+ sorts them by Album and Title tags.  

Probably can find a way to synch these, but no problem for me to re-tag and transfer manually.
