Flat Button 2 Font weight?


I’ve purchased Flat Button 2 to allow more styling that the Foundry included one but Im having trouble working out how to set a bold font weight ? There seems to be only a size option… I have put ‘custom’ in the dropdown and ‘Raleway’ in the fied (the google font I want) but now I need to make it a bold variant.

I can do it with CSS but would like to know if its possible without resorting to that.

Many thanks,

Font weight is not a feature of the Flat Button stack.
