Use stages as a condition in campaigns

I would love to be able to use Stages as a campaign condition. It is currently not available as such.

Instead of having to create segments that mimic lifecycle stages (because segments are actionable in a campaign), you could use a combination of stages/tags to create funnels and stages for multiple products.

Tried to +1 this but the vote button now says “Limit” and I get a 403 error.
