Change Decimal Key in Substance Designer

Hi,

I am using Substance Designer with Polish Keyboard layout and language set to "English" in Substance Designer. The problem is when i press decimal symbol on numeric keyboard I got "," (which is native for polish keyboard layout) insted of ".". However Substance Designer is not accepting "," as decimal symbol and keep ignoring it. Is there an option to change it? All other softwares I use does not have this problem: Blender, Photoshop, even Substance Painter accept "," and automatically change it to ".".
