EDITING: In the file properties of an Impress file you can define some user defined values. Example: Name "Subject", Type "Text", Value "Stress reduction" (sorry if the keywords are wrong, have only a German version). It should be possible to use the value "Stress reduction" in an Impress page or master by using "Insert - Field - More Fields" like in Writer.
Steps to Reproduce:
1. Add a user defined property
2. Open "Insert - Field"
You can just select predefined values
You should be able to select the user defined property like in "Writer"
User Profile Reset: No
