Add Offset slider to Plant Path and Custom Path

Dear D5 team, can you add an Offset slider to your Plant Path and Custom Path?
Currently you only have Random Offset slider. Sometimes when planting creepers, I need the plants to ‘push’ out a bit from the planter box but as the path need a surface to snap on, it is very difficult and I need to create a fake surface for the path to snap and hide it afterwards.
