Seeking Lawyer Count Data for LATAM Law Firms

Hi team 👋 I’m building a target list of law firms in LATAM and need to know how to get or filter by the number of lawyers per firm, not just total employees. Is there any enrichment or field (like Lawyer Count or Attorney Headcount) that provides this? I tried to apply a formula to combine job title+head count but it didn't work, could you help? Thanks so much! 🙏
