Copy Basic & Forecast dates from Project Definition to WBS Element

Hi Experts,

We have a requirement to copy the Basic and Forecast dates entered in the Project Definition to all the WBS Elements that are created for that Project Definition. We tried to implement substitution but the fields for the WBS Element dates (Table PRTE) is not available in substitution and we were also not able to add the table to substitution.

Is there any other way to copy the Basic and Forecast dates from the Project Definition to all the WBS Elements. Please advise.

Thank you!

Regards
