Smile [Q] swiss french external keyboard 70 IT

I have a 70 IT. In the external keyboard settings there is no possibility to choose for a French Swiss external keyboard. I have an arc Microsoft external Keyboard which works perfectly. Bought in Switzerland, it is French Swiss language. Is there any way to have it correctly recognized? As internal keyboard I use anysoftkeyboard with Swiss French settings, super. Is there a possibility to link the external keyboard with the internal anysoftkeyboard? thanks
