join 3 layers of dirrenent zooms into one mbtile

I have 3 .geojsons of water_polygon. I would like megre them for one mbtile file for 3 different zooms.
When I use
tile-join -pk -o water.mbtiles water_1.mbtiles water_2.mbtiles water_3.mbtiles
I have water.mbtiles that consists from 3 layer on preview, but I need to have just one layer on preview. I tryed use -l tag, but it doesn't help me.

Start with the tile-join command and the three water_1.mbtiles, water_2.mbtiles, and water_3.mbtiles inputs described in the issue. Determine whether the requested result is supported and what change would make the three zoom layers appear as one preview layer; done would need a reproducible command or an implemented behavior with verification.
