Sync 'plan' fitness with 'real' fitness chart

Hi,
I am using a Training Plan feature to schedule the training. The ‘starting fitness and fatigue’ option is great when creating a new plan; however, when I want to update the existing plan mid-season, the fitness chart in training plan is not synced with the actual (real) fitness, as it only accounts for the planned activities (assuming they were all executed). Naturally, skipping planned activities or executing unplanned activities result in ‘real’ fitness lines deviating from the planned one.

Is it possible to synchronise the fitness chart in the training plan with the ‘real’ fitness chart? For example, a manual or automatic sync to a selected date. Meaning that any updates to the existing plan would build on the real current fitness.

An example of real fitness line:

Thanks in advance. Best,
