I suspect you're looking at something like creating Custom Properties which will contain the information you want in the description.
By default, SolarWinds shows the Custom Properties for a node in the Node Details page (you can select which Custom Properties are displayed.)
Alternatively, you could write an Inventory Report and add the relevant Custom Properties to it, then create a link to that report or create a new View on which you will show the Report as a Resource.
Hope that gives you some ideas. Feel free to drop me a line if you want any further help (although probably best to follow up on here so that others can benefit too!)
