Is there a roller mat with feed mode?

[MartinM]

In the past I never used mechanical filtration, mainly because I'm a fan of all the life that I get by feeding a lot. However, I'm seeing the benefit of keeping detritus down in my system with SPS, so I'm wanting to use a roller. That being said, is there a roller with a feed option so I can have the water bypass the roller when I specify? Obviously turning off the return pump for an hour or so after feeding is a bad idea and I wouldn't want to do that. Suggestions are welcome, thanks!

The RedSea Reefmats have a feed mode. I don't believe there is any way for the water to bypass the filter---during feed mode it just disables roll advancement.
