So, by "Google Calc," you mean Google Sheets?
I was not aware there was an importhtml function! Very cool!
For those who are not as familiar with Google Sheets: What Magnus did was use a function within the spreadsheet to import data from the surname webpage, and it creates a list that you could then sort by profile manager.
One thing you would need to do is copy the profile manager name down into the empty cells in the list where the webpage shows quotation marks. For example:
One caveat after playing with this a little: It's going to be difficult to determine which profiles are being managed by the same manager in the name shown above the empty cells, and which profiles have no manager.
Also, if you want to manipulate the data once you pull it into a spreadsheet, you would need to copy it and "paste values only" into a new sheet, otherwise, you'll get an error.
