Yes, that is possible. In the properties mapper, either select an existing or create a new node configuration. Then, select "Multiple" as "Template" (the row between configuration name and "Mappings" table). This will add a new row in the "Mappings" table. Select the new row in the "Mappings" table. Choose the property that determines the shape as "Data Source" (first column in "Mappings" table). Then for each (value, shape) pair add an appropriate row in the "Conversion Details" table at the bottom of the properties mapper dialog. I.e. enter the value in the first column and select the desired node template in the second column.
