[NSFW] Filter integration in profile users search [profilegrid_users]

Good morning,
and thank you for your attention.

I am writing to ask if it is possible to integrate an alphabetical search filter.
On the page with the shortcode [profilegrid_users] we would need to add the alphabetical filter.
Under the search field we would like to add all letters of the alphabet and when one is clicked on, all surnames with that letter are searched.
If it is necessary to buy the plugin for this integration, I will not hesitate to purchase it.

I thank you in advance for your reply.
Best regards
Flavio (MGEL)
