Adding a category to a product block

Is it at all to add a product category to a product block.

I have a category for sale items.

I would like these items to display in a block on the main page. By default the product block has things like newest and most popular OR you can manually add products. Manually adding is time consuming and will be hard for the client to keep on top of.

If a product category could be added rather than just individual products this would mean that the block is now dynamic and as soon as a product is added to the sale category it could automatically display inside that product block


This seems to be a nice feature. Would you mind to post it to Uservoice: ?
