Feature Request: Only one watch

Hi,

my Company recently switched from a self-written ERP-Tool to Monday. This tool had one advantage over Monday, which I would like very much to be implemented as a feature: You could only work on one project at a time, meaning you started the general watch, worked on Projekt A and when you were finished you booked your time on Project A. Then you could restart the watch. What happens to me continuously: I start a clock but after I finish I forget to stop it. This mostly happens when I am interrupted with a user requests but also when switching projects. I would like an option to limit the number of max clocks running at one time to one. This would help me very much and solve all my Monday problems.
Thank you and yours sincerely
Stefan
