Booking in timesheets for multiple projects

Hi all,
explore working with ERPNext using timesheets.

In my case, We often do work that can be reused in different projects. Due to contractual reasons this results in an employee booking timesheets in multiple projects.

Problem: If an amployee books e.g. 8am to 9am in project A he/she cannot book 8am-9am in Project B, too. What usuallly makes sense is a hussle in my case. Is it possible to disable the consistency check, resulting in the possibility to let one employee book the same periode of time in multiple timesheets?

Thx for your advoce!

Regards Gerd
