Hello @Clara10, thanks for joining us, it's great to have you on board! 
At this moment is not possible to select an exercise goal based on a number of times you've exercised, the goal can only be set by days. However, I understand how this feature will be very beneficial for you and many people, which is why I would like to suggest you to submit a suggested idea, where members of the Community can vote for it and add their comments. This is truly the best way to make your voice heard.
I hope this can be helpful, give it a try and keep me posted in case you need anything else!
