Lifting of ball in play

[DeanoMK]

normally I cant repair a pitch mark on my line of play

I thought you could repair pitch marks/damage even if it's on the line of your putt?

With your using the words 'line of putt' I assume you are referring to a ball on or near the putting green.
You need to look at Rule 13.1c Improvements Allowed on Putting Green
