It’s possible you can tap into the supply line under the sink with some kind of valve that t’s off. I’ve never actually seen this, just read about it, so I don’t know what it would take. But a little online research should give you the answer.
If you go all electric and use Spike Brewing non-vent boil cover, you could do it in the basement without adding any venting to the outside.

I thinking of going this way so I don't have the cost of adding a vent hood and punching a hole through the concrete wall.
I saw this in a brewery one time and thought it was pretty slick. The steam from the boil is directed into a tube that turns downward and a small spray of water condenses the steam in the downward facing tube and it went down the drain. This one has a pump that creates a fine mist that lands in a bucket. The water can be recirculated. Very compact, but a little pricey. But so are hoods and vents.
That's what my wife complains about too! I'm glad I'm not the only one.I still seem to spread out my shit over most of the kitchen...
