Bookmaker options for over round

[Muzza181]

Hi all,
New to Gruss so go easy but I am looking to sell the book at over 1.25% now on other software out there it’s done automatically but it’s too pricey and was looking to see if this can be done here,I see the Dutch options but no profit on the lay side when adding all selections is there some sort of way I can adjust or get a margin on lay odds, so I can do a one click strategy? Thanks
