When want to link parameters it opens browser where you need to search for folder where your part or excel file is. Many times it happens that browser is set to last visited folder even it was opened in another project. If want to link parameters from another part in same project it make it difficult to find path to desired folder. It is time wasting and it is possible to go wrong and choose wrong parameters if there are similar folder names.
Add button/option WORKSPACE in browser window to go fast to project folder - see image below.
