changing datatips of box plot

Hey there, I am stuck on this problem for about a problem and there isn't much help for my particular plight online. I have plotted 13 different electrodes for EEG and their data into boxplots using the subplot function. I am trying to make custom data tips for the outliers in the boxplots. I tried using the UpdateFcn but it doesn't seem to work with boxplots and all the queries i found online work for scatter plots not really for boxplots.

A snippet of the plots i am working with can be found here,

So far i have found that when i get to datacursormode.dataCursors.get, i can access the structure that has all the values stored and i can see all the information that is being populating the data tips,as seen below

 cursorMode.dataCursors.get 
            Annotation: [1x1 hg.Annotation] 
           DisplayName: '' 
           HitTestArea: 'off' 
          BeingDeleted: 'off' 
         ButtonDownFcn: [] 
              Children: [0x1 double] 
              Clipping: 'on' 
             CreateFcn: [] 
             DeleteFcn: [] 
            BusyAction: 'queue'

                   Tag: '' 
                  Type: 'hggroup' 
              UserData: [] 
              Selected: 'off'

       BackgroundColor: [1 1 0.9333] 
             TextColor: [0 0 0]

            MarkerSize: 10

       MarkerFaceColor: [0 0 0] 
       MarkerEraseMode: 'normal' 
             Draggable: 'on' 
                String: {'Outlier Value: 4.0256'  ''  'Observation Row: 25'  'Group:   '  ''  'Distance To Median: 5.9022'  'Num IQRs To Median: 4.8328'} 
               Visible: 'on' 
             StringFcn: [] 
             UpdateFcn: [] 
         UIContextMenu: [1x1 uicontextmenu] 
                  Host: [1x1 line] 
           Interpolate: 'off'

String: {'Outlier Value: 4.0256' '' 'Observation Row: 25' 'Group: ' '' 'Distance To Median: 5.9022' 'Num IQRs To Median: 4.8328'}

I want to change the string values that are displayed to change the labels and insert another value in that string to display. I want to use the value of Observation row as an index to extract the name of the subject who is outlier from a matrix that i created earlier which i should be able to access from the workspace, and then add that value to the string that should then display in the data tip.

Any help i can get, i would really appreciate.....
