Expand Database Without Find People Feature: Alternative Methods

hey everyone, i just created a table using "find people" feature from a company table I have, but for the sake of testing, I just created 50 rows with person information to test some prompts using claygent and chatgpt Now i have some outbound messaging for each person and I want to expand to more people using the same company table i have used previously. How can i do it without running the "find people at these companies" feature? I really want to get more people to table i'm working on
