it is possible when i see this product:

[url]Instant Demo - CS-Cart Multi-Vendor Demo Try Free for 15 days

In the title appears:

Computers :: Handhelds & PDAs :: HP iPAQ RZ1715 Pocket PC - CS-Cart. Powerful PHP shopping cart software

But i what to only apper:

HP iPAQ RZ1715 Pocket PC

The name of the product in first place. It is possible to do this will all products only changing the order of the meta? I know that is possible to do individually, but all at the same time, it is possible?

Best Regards,
