Add custom field to history subpanel

Hello All
I am trying to add a custom fiend, that belongs to the Calls module, to the History Subpanel of the Contacts.

I have tried to follow this link, but it does not work.

Is there any special way to do this in SuiteCRM

Thanks a lot.

I too am looking for this option. I do have Admin privlidges and can go into Studio. I do see areas to tweak the fields of any type of data in SuiteCRM. However, I can find nothing for editing and adding to the history section. Would be interested in working with photo fields in notes.

The link above that doesn’t work is still available from the wonderful Wayback machine:
