Dispatch to read custom property from a drawing border and add it to the file datacard

I am trying to take a custom property from a drawing border and then assign it to a drawing file data card.  This is because I am bringing legacy data over into a new vault and I want to populate the file data cards.  The file itself does not contain any custom properties as the drawings are driven by the properties in the models.  Last week I got help from in taking file names and adding them to the file data card using a dispatch.  I am now modifying that dispatch.  Currently the description updates with "(Find)Description" which is the value set.  This is where I am not sure what this value should be.  Any help with this would be appreciated.  Just for further info, the only reason I am doing this is because we are bringing over a mass of legacy data and this will save me having to enter a description in for a lot of components.  When people are creating files in the new vault the description and all other properties get created via a template in the usual way.
