Can I "swap" weeks in my BT Logs

I am using the HIM BT plan.  I'd like to swap week 10 with week 11 and week 11 with week 10.  Just flip-flop them. 

I'd use the move/copy/delete option but if I move week 10 to week 11 it will have double the planned data.  Then if I move Week 11 back to week 10 it will move double the data .... This makes sense in my head sorry if the explaination is convoluted.

Is there any way this can be done other than manually copying and pasting each individual workout back and forth?

Thanks!
