PowerGeopak V8I SS2 - Excel (2016) VBA

I can export tags (TagEditor.mvba) from MicroStation to Excel.  The Excel file and DGN folders are hard coded.  I'm looking for assistance in vba coding to be able to open a file window and navigate to the file locations.  One is to navigate to the excel file and the other is to navigate to the dgn folder location to import the tags from.  I can update the tag values from Excel to MicroStation, but only by a single selection.  I'm looking for assistance in vba coding to be able to update by selection set from Excel to Microstation and be able to open the Excel file as well.  I'm still working with my IT Department for purchasing Jon's FlexiTable, so for the time being, I'm trying to move forward with what I have.  Any assistance will be greatly appreciated.
