Hi

So I am creating my first course and want to know if there is a way to change the Udemy default numbering system for lectures.
It seems that Udemy numbers the lectures 1.....99 regardless of the sections each lecture is in.
I would like to have this numbered as 1.1 (Section 1, lecture 1), 3.5 (section 3, lecture 5) etc. I'd also like to be able to sub-lettering to some lectures such as 3.5a & 3.5b etc. Is this possible or am I stuck with the default?

Thanks
