Section level Timer - LTI


I am trying to integrate a timer in our open eDx instance, for timed exams.
While we can offer timed exams through open eDx (where the timer is enabled at the sub-section level), I am looking for a timer at a section level.
Would there be any LTI available for the same?

Thanks in advance.

Doesn’t LTI work only at the component level?

LTI works at the component level. However, the existing timer in the platform is at a section level. I am looking for an external timer which can work at the sub-section level.
