Drinking water filter tap, with magnesium, no RO?

Hello, We currently use a filter jug with BWT cartridges that add magnesium, and we like this effect. But I think it would be nice to make the water somewhat softer, maybe somewhat cleaner, and much more convenient by adding a stationary filtering system under the kitchen sink, with a tap coming out of it. However, I don't…

Hello,
We currently use a filter jug with BWT cartridges that add magnesium, and we like this effect. But I think it would be nice to make the water somewhat softer, maybe somewhat cleaner, and much more convenient by adding a stationary filtering system under the kitchen sink, with a tap coming out of it.
However, I don't want to go Reverse Osmosis. It takes a lot of spaces, wastes significant amount of water, and costs a lot too. I'd prefer a "normal" multistage system, something like this https://www.amazon.co.uk/dp/B09Q5LYKLZ/
And yet, I want to have added magnesium... and I can't find the right cartridge
I could find only two magnesium-adding stationary cartridges on Amazon:
The BWT all-on-one single cartridge system https://www.amazon.co.uk/BWT-MMDWFKIT-Inline-Drinking-Magnesium/dp/B0815C2C19 , or just the cartridge https://www.amazon.co.uk/BWT-MMDWFCART-Mineralizer-Replacement-Cartridge/dp/B0781ZPTN1 . This is intended for use on its own, and as this is a single filter, I doubt it would do a much better job than my existing jug? Or maybe I can add it after a three-stage system, but that's kinda a lot of flexible pipes, all pressurised, asking for trouble?
Remineralisation cartridges intended for reverse osmosis systems, such as https://www.amazon.co.uk/iSpring-FA15-Alkaline-Replacement-Cartridge/dp/B00FBLGD1S . I suspect it would make non-RO water too hard. I just want to add some magnesium, not other minerals.
So, which options are best for me?
