One of the options is to create a new calculated field that results in YTD. You can use this new value for reporting.
The New calculated item YTD will only be filled if the DayOfYear is less/equal of actual DayOfYear
Of course it all depends on the way you want to show your results and how your definitions of YTD etc. exactly are.
For MTD you can add that also the months are equal. etc.ect.
Greetings and good luck.
