Question about use many proxies [proxy]

Hi. I have a project of i need to insert informations in databases, but i need to change the proxy of each insertion.

The part of insert the information in DB, i created. Katalon read my XLS and input the data in the database. But now, i need to create a proxy changer, to the database acept my connection.

My data example is like DB_NAME | DB_FLIEND | ID | NUMBER | INFORMATIONS | PROXY

I need to change the browser proxy to “PROXY”, and after go to DB_NAME, DB_FIELD, and input the ID, NUMBER and INFORMATION. I can make all, except the proxy changer.

Have a way to make this in katalon? And how i can do it? Someone can me help, or send a good tutorial to this?
