Transferring Remaining Credits from Secondary Clay Account to Main Account

Hi there, we have two entities each with their own Clay account: Main: https://app.clay.com/workspaces/315526 Secondary: https://app.clay.com/workspaces/297638 We're looking to close the 2nd account but we have 4k credits left on it - is there any way to move those credits over to our main so they aren't lost? Thanks!
