Hello Tamoran,
I have checked the pdf and the schedule give for 5 batches " Sr B Edges", "Sr A Freeskate", etc.. I can write Macro to Hide / Unhide cells when check box clicked as you required. I have 5 years experience in Excel VBA programming and completed 400+ projects. I never ask for payments in front. You can release the agreed milestones once the task is completed and you're happy with [login to view URL] my reviews to confirm my work quality
With Regards,
Sai
