HTC Desire S – Text message block editing / deleteing from PC ?

Hi,

My number of text messages is growing and the longer converstaions have slowed down the time it takes to load the message.

On my old Sony Ericsson i had a PC suite which showed every text message and allowed me to delete multiple or individual texts – is there a PC suite that would allow me to do this on my HTC Desire S ?

The HTC Sync programme doesn’t seem have this feature and i could really do with it !

Cheers
