[BUG] Not able to open modal with currency preselected
Hello. Thank you for great product, it is awesome! 
I need to open a modal with currency preselected. I did not found any code for that in bitcart.js, and also not able to use hacky way like modifiying dom. 
Please tell me a quick-and-dirty way to predefine currency on modal dropdown. As I understood it is Vue, but I don't know how to address your app and which element to make desired selection on dropdown. 
And also please implement it in modal options.
Thanks
