7 – How to override Search API index field machine name?

I am using Search API and Search API Solr modules on drupal 7. I have also drupal 8 and drupal 9 sites, and all those sites are indexed on the same solr index. So I need the same machine name for indexed fields. For this purpose, I need to override marked machine names.

For drupal 7 I can’t find a field mapping solution like Search API field map module for drupal 8, 9.
Is there any solution to override those fields’ machine names in index creation?
Thanks.
