As what @jacob.small was eluding to, we are just wanting to know how much effort have you put forth initially? Have you researched the forums to see if your question has been asked prior with a resolution?

FYI. Those values can be retrieved and changed, but not like a typical parameter. So more than likely you will have to install a custom package like “Fabrication API” in order to get the nodes to do what you are wanting to do. Be aware, that package hasn’t been updated since 2018, so the nodes may or may not work completely. However, if you try create a graph and get to a point of failure, the effort will be noticed and others will be more willing to guide you the rest of the way. If you don’t know how to install a custom package, there are definitely several posts in the forum on how to do that.
