Fractional shares for Swiss Stocks + ETF

As much as I can see none of the Swiss Stocks can be bought in fractions.
Even worse with the ETF for the Swiss market, Xtrackers Switzerland UCITS ETF 1D (DBXS), which has a minimum quantity of 2. [maybe even make it available via LSE rather than Xetra?]

Please enable fractional shares for them (where it makes sense from their stock price)
