Mobile phone on checkout - invoice

[kraken234]

Hi,

 

I have question. Im using one page checkout on my site. Phone is required field. When customer want to use different invoice address, he also needs to write number again, but in this position is not necessary.

 

Is there any way to have in checkout page phone_mobile required, but phone_mobile_invoice not? All setting in Prestashop looks global for normal and invoice address.

 

Thanks for reply
