You may opt to copy the existing contract to make another contract with the same account by clicking on the "copy" button on the right side of the contract.
This will open a box similar to Add New Contract. Edit the details you wish to change such as contract price and the contract's new end date, then click on Save.
You have now created a new contract with the same contract number to indicate that it is a continuing contract.
