(Classic) Defining start number in ordered lists

[Silvercat]

I swear I had read how to do this somewhere, but I can't find it now. I have an ordered list that is broken up into sections with headers. I want the numbering to continue through the whole list. So in the second and further sections, how do I define what number the list should start at?

Thanks

! Ordered list

# First item
#* First item child
#* <span> First item child <br/>
                That spans several lines
</span>
# Second item
