Stop retroactive changes to nutrition targets/calories etc.

It would be amazing if manual adjustments to nutrition targets could be applied to future entries only. Currently, when one changes a target it is applied retroactively which then makes all past entries and reports inaccurate. For example, I’ve been tracking pregnancy nutrition needs and will soon need to amend these to accommodate new requirements for breastfeeding - by making this change my past entries while pregnant will all be changed to breastfeeding nutrition requirements. It’s such a frustrating issue and seems like it shouldn’t have ever been a problem in the first place as people’s requirements can change all the time for various reasons.
