Edit Fund to Require Projects to Balance

Good afternoon,

I am wondering if there is a workaround for editing a Fund within FE NXT that previously didn't require Projects to Balance. We would like to edit this Fund so that Projects would now be required to balance, although, we would still like it so that a Project isn't always required.

As you can see in the above screenshot, right now the option to edit this is greyed out. We have been using this Fund for a while, so there is a lot of data already entered, and we don't want to lose this data.

Does anyone know how we could do this? Thanks in advance!
