WP bakery vc_map param_group

Does anybody know how to provide default values for multiple fields in param_group?

Example if I have following code, this will create one instance of this group with values ‘my_headings’ and ‘my_content’:

Is it possible to provide default values for multiple groups to be visible on start, so for example
group 1:
‘my_headings’ , ‘my_content’:

group 2:
‘my_other_headings’ , ‘my_other_content’:
