Patch a dozen GLP Impression Fixtures
Got to Patch -> Edit Fixtures -> Sort by Function
If you go to the 'CTB' parameter, select the column header (black row) above 'Default Path', and hit Set, you will be able to edit the default path of all fixtures.
If you go to the 'Colour' parameter and do the same you will not be able to make the edit. I believe that this is because the first cell you have selected is a hashed out cell for the slotted colors.
