Is there option to have the Form Builder version specified for each form?

I am wondering if there could be an option to have the version specified by "Form" rather than global.  The reason I ask this is that as you role out new versions of the solution, being able to selectively move and test forms to the newer version would be a much better way of migrating rather than all or none. 

Unfortunately it is not possible to specify the Form Builder version for each form. You can only set the form builder that you will use globally.  However, you can easily switch the form builder that you want to use by opening the Account > Settings and selecting your preferred version.

Please let us know if you need further assistance,
Regards.
