ACF add-on

On a WordPress Multisite, we use Broadcast to copy posts from the primary site to the sub-sites. The posts can have a Custom Author name/title/image (ACF fields) that get Broadcast along with the post, sort of. The Text fields get passed on without issue, but while the image does, it is being passed as an image ID:

  '_auth_job_title' => 'array (
  0 => 'field_663c1be40b4a6',
)',
  'auth_headshot' => 'array (
  0 => '4906',
)',
  '_auth_headshot' => 'array (
  0 => 'field_663c1c1c0b4a8',
)',

The problem is that the posted image ID (4906) ends up being not found on the sub-sites where the image ID ends up being something different, due to the differences in the Media Library contents.

I realize there is an Add-On plugin for ACF fields (which we are not using currently) but my question is, if I bought it, would it handle and correct this problem?

Thanks.
