rearranging plan

Not all at once.  Though we are finishing a new feature allowing one-step full plan customization.

Two options you have now:

1. Import the plan but see if you can 'stagger' it up or down a few days so it fits your schedule better.
2. Once a week, say on Sundays, go to only the upcoming week of the plan and use the 'copy/move/delete' tool to move around the days needed.

   This way, it will only take you a few minutes a week to customize the upcoming week instead of trying to do the entire plan at once.  *You can go through the whole plan or a month at a time to customize, it just takes a bigger chunk of time upfront.

Let me know if you have any questions on this.

Got it. Thanks for the fast reply.
