Freeze training option

Sometimes, for various reasons (for example medical), you cannot train. Being in the middle of a program, I think it would be useful to have a "freeze" button, with the addition of the reason and the addition of the mention if any form of training continues and at what frequency and intensity (for example the doctor won't let me in the gym, but allows me to swim); in this way, the application knows where I interrupted the program, for what reason and if I continued any form of training, so that when I return to the gym, it builds the best version of training for me based on the existing data.
