Need to modify Signature Clause Column Titles

Content (required):

Hi, We have a requirement to modify the signature clause signature title. Currently it is showing the Business Unit name in the column title (Signed for and on Behalf of 'BU Name'). Business Unit name is irrelevant for us and we like to have the LE name instead of BU name. Please advice how can we do this change. This is a critical requirement from Business.
