Unable to use cross reference variable feature

Summary:

We have issue while creating the contract template as per the clients requirement for procurement contract. Please find the detailed description below:

In Aldar we have a requirement to define the entire one template as a clause in application although they have different sections and clauses in there Word file. For Ex: '250219_Template Services Agreement (Short Form)_Final' is a word template. Under this template client wants one single section as ' Short service agreement section' at the time of creating template in application. Under this section they require one single clause 'Short service agreement clauses'.

In this case we are unable to create cross reference variable for their clause reference numbers. Please let us know how can we create cross reference variable in this scenario.
