Default value for Date and time attributes

Hi, 

There is only an option to set default value in the value of Date and time attributes, [%CurrentDateTime%]:

When you work with dates, and you create the object with that variable by default, the format could be with different hours than 00:00:00... and then when you use it to compare in microflows, it doesn't work correctly

It would be helpful if there are expressions like [%BeginOfCurrrentDayUTC%] to set like default value

Thanks
