Make content in seperate MySQL table editable

Morning all,

I have a table in the same MySQL database as my Perch files with information about stockists of my clients products which is being displayed on a searchable map. Can I make this data editable within the Perch admin panel?

Because the customer provided me data in a CSV file with name, address, website,lat/long it was easy to import that in to a table and link the map to it (See Stockists Page) - but I now want her to be able to edit the content of that table in Perch. Or is there a way to import the data to sit within the existing perch_content tables without having to manually input the data?

Cheers, Josh
