Changing initial folder of Visor to other than myDocuments.cannedSearch

TotalFinder’s Visor opens with the systemwide predefined search myDocuments.cannedSearch. I would prefer the Visor opens with a folder of my choice, e.g. the Desktop. Is it possible to set the initial folder by an option/preference?

(For reference, the cannedSearch is located here: System -> Library -> CoreServices -> -> Contents -> Resources -> CannedSearches -> All Documents)

A related but more ambitious request was posted by @replete here: Can I trigger the TotalFinder Visor to load a set of directories?. I would be happy to just being able to define the initial folder myself through an option/preference.
