@Keith_Harrison , I don’t think there is a dedicated node for this purpose. However, the solution does exist but would require a bit of coding (not “crazy complex”). What you need is so-called Static Data leveraged by Code node.
Some examples of its usage could be found on this forum, for example,
like @ihortom said the static data is a solution without any external tools needed.
Another option would be to get something like airtable or baserow to store the data and keep overwriting the same record so you always only store the latest data and then you can easily retrieve that when needed.
This might be an easier option to get working for you, also a tool like that is nice to have for other usecases.
