Cannot input yeartotal in adhoc

Hello everyone,

I am trying to input the number at YearTotal level in both Form and Ad-hoc mode.

But I saw that in the form I can input easily and it will automatically spread based on the Account's Time Balance type.

However, when using ad-hoc mode, I cannot input the data at YearTotal (parent) level. The cell is greyed.

My question is:

Can I input data in ad-hoc mode and it will spread the inputted data like it did in the form?

Thanks!
