Custom origin for vc_acf shortcode

I’m wondering if it would be possible to specify somehow a custom origin in the [vc_acf] shortcode. As an example, let’s take:

[vc_acf field_group="72796" field_from_72796="field_657863498c621"]

The idea would be something like:

[vc_acf field_group="72796" field_from_72796="field_657863498c621" custom_post="XX"]

So instead of getting the context from the actual place where the shortcode is placed, it can go to a different place for getting the fields from there (custom_post in the example).
