The short answer is no.
But..., the wonderfull thing about Boomi is that there is always a way, and the thing you could do is to create a process property where you store the process execution ID.
In the same process you create a csv-file with named process execution ID. In that csv-file you append all the document properties, with a unique key and the document property.
Next time the process is executed, you get the file named process property "last process execution ID", split the content of the file into a document cache, with the unique keys and you are ready to perform the appropriate lookups in the cache where you have all the records from the last process execution.
If you need an example, please write back to me.
