random global content tag

[Bealers]

Hi

I was about to sit down and start writing a simple tag when I thought I'd better check that it's not been done already.

Say I've got a number of global content blocks all with a name beginning "snippet_"

I now want to pick a number of these content blocks by simply adding to my template a tag along the lines of
{random_global_content type="snippet" blocks="2"}

On a differing template I might chose to only show one block and from a different pool so I'd simply adjust the type and blocks parameters.

Can this be done using an existing technique?

Cheers
