Klaviyo signup forms with variants and trigger via javascript

Hello,

We are trying to see if we can utilize the klaviyo forms while running an A\B test and trigger the form for specific variant base on our own logic on the website.
i only saw the ability to display the form via 
window._klOnsite = window._klOnsite || [];
window._klOnsite.push('openForm', 'FormID');
in the documentation it states the following:

• When a form has an ongoing A/B test, this API simply triggers the form’s display. It is your A/B testing logic, which is separate, that determines which variation displays. If you have an A/B test where a variation of your form has a custom trigger, you will still need to add custom trigger code to your site.

is there a way that we can trigger the form with the specific variant, i.e. something like:
window._klOnsite.push('openForm', 'FormID', ‘variantA’);

thanks for your help,
