It would be a great time saver to have the ability to populate the custom properties for volumes and interfaces with the information in a Node. We frequently need to go in and readd volumes/interfaces to various nodes and in each case we need to input the custom properties over and over. Inheriting properties from the node would save quite a bit of time.
Considering that there are other issues that make this process take even longer (magical ? characters showing up on copy/paste, only able to edit one properties page at a time) this functionality would great.
