How to make value field for "Assignments" property editable for a Task in jBPM Web Designer ?

Issue

• In the previous version of BPMS 6.0.0 it was possible that instead of having to expand/open the pop-up window of Editor for Data Assignments to edit the data assignments property's value fields (i.e. change any of the From Object , To Object etc from the Data Input/Output Assignments) individually, users were able to edit the string (e.g. procesVariable -> taskVariable) directly from the combo-box (see the NonEditable.png attachment) available for the Assignments property in the jBPM Web Designer's right hand side property window. Usually by copying the string out, making changes in a text editor, and pasting the end result back in. However, this is no longer seems to be a supported feature in the newer releases of BPMS 6.0.x . Is there a way that these properties can be made editable again in the future releases?
