How to add map new field from streamline interaction to incident ?

Hi,

I had wanted to have the title field in the streamline interaction, so that when my helpdesk open a case the title is also auto map to the respective module "brief.descirption" field,

I had add a new field "title" to the interactionDelegate table, and had updated the code in script library streamlinedSDService line 4 with the new array element "title" .

was able to get the title auto popluated for change and request module but for incident module it keep showing as the first line of desciprtion field.

Seeking advice on where can i find the mapping for interactiondelegate to probsummary?

Regards
