Can a RoboHelp snippet that contains a list, be appended to an existing list in a topic?

I have several procedures that use the same steps as part of the procedure to create something. I would love to use a snippet for these common steps. However, when I try to create a snippet of these numbered steps and then reuse them in the procedure list, the snippet step numbers all say 1 instead of picking up with the next available number in the existing list. For example, my list in the topic has steps 1-3. My snippet contains the remaining steps - which should be number 4-12. How can make this happen?
