Currently the TestStand sequence editor does not allow you to edit selected properties as you are suggesting. As you said, the only option is to enter them manually, or create a tool that operates on a sequence file and the tool must use a path to the property that you want to edit in some way. Currently the TestStand engine does not allow the sequence editor to specify what the currently selected property is creating a tool must edit the sequence file or step and you must supply the path to the property. We hope to address this in the future.
