We have default Historical Summary section in edit view of Account module like below.
After clicking on that link a pop up opens (see above screen shot second) which contains below fields of Meetings, Calls, and Task.
Point First : I just want to add some more fields of Meetings and Calls in Historical Summary in Accounts Module.
Point Second: I also want to add custom subpanel data with default Meetings, Calls, and Task data.
How do i add Custom fields / Custom Subpanel data in Historical Summary in Accounts Module?
