Converting Q3 from low boot floor to high boot floor

[Epsomsalt]

I am in the throes of buying a 2018 ( reg April 2018) Audi Q3 1.4 S Line Auto. 
 

the car has a low boot floor I.e. carpet sits straight onto the floor, I would like to know if it can be converted to a higher floor to accommodate a foam insert to house a space saver spare tyre??

if so any idea of cost please??  
 

Thanks

Chris

I'd recommend you look at buying the full kit on eBay. It's what I did with my wife's Jag.
