How can I import a Symbol Set to MT5

[paddespear]

Hi, I am looking to create a list symbols to save as a 'set' in MarketWatch (over 1000). I know how to add symbols and how to save a 'set' in MT5 but my broker has over 3000 symbols of which I only wish to scan and trade against 1000. Is there a way I can upload an excel file or a (*.set) file with the full list of 1000 symbols prepopulated to save me from having to add them one at a time to the MarketWatch list? Thanks
