Supplementary contract to Upwork's default contract

[0b0084d0]

How can I upload another contract that supplements the optional service contract terms? Does freelancers sign contracts by checking off the agreement on Upwork instead of writing signatures? Should I use other software (like DocuSign) to sign the supplementary contract after we started the project on Upwork?
