Can you set the default country code on a Zobot 'tel' input card?

Can you set the default country code on a Zobot 'tel' input card?

Hi

I'm using input cards on my Zobot. The 'tel' input card for phone numbers defaults to adding a +1 (USA) country code. Can I change this to +44 (UK) because all my customers will be British? The documentation doesn't mention this as an option so I suspect it's not possible but I thought I'd ask anyway.

Many thanks

Steve
