From MiScore update 23rd March release, the ability to enter the number of putts per hole will be available.
The interface for this is disabled by default however if you wish to store number of putts made by yourself and your playing partner, access the Setting area under Menu tab. Turn on 'Putts Enabled' property.
When on, after you enter the gross score on a hole and swipe left, the putts entry interface will be shown.
You can disable this at any time during the round via settings.
This feature is ideal for Monthly Medal Stroke rounds that have in-conjunction putting comps. There is a support export report from the MiClub back end system that the club can generate which collates all the putts per hole to give an order by best putts per round.
