Add existing field from Accounts to Calls

First of all, I would like to congratulate you on developing this excellent tool.

I need to add the phone_office field (of accounts) to appear in the Calls dashlet. Unfortunately this field is not available in Calls and would like to appear on it.

If you can help, with a step by step, thank you!

I’ve already tried adding a phone_office field in Calls, but it did not work.
