OCPM - Adding additional columns without specifying them as custom properties

Hello,

we are currently playing around with OCPM on a non-sap system.

We want to add aditional columns from the source table to the OCPM Object.

However, we would need to add each as a custom property.

Anyone found a solution to add them all similar to "select * from sourcetable"?

Thanks for the help!

Best regards

Patrick
