Store custom information published in custom fields, to a new table so that when SC is uninstalled, or reinstalled, it gets retained when it is back online. Perhaps tie it to a unique GUID or similar.
There are times when the "user" is a generic name, and we use the custom field to note which user or which specific location in a building that machine is. The problem is that after the software gets uninstalled, so does the information related to the note. We need this to persist. Perhaps a new table which contains all the "custom" information, tied to the GUID of the software or some other unique ID.
