You cannot. This is not a missing feature in docx, it is simply not a thing in all of OOXML.

I stand corrected, as @eatkid points out there is the @w:firstLineChars attribute. Sorry!

But you know, this is a very common function in word

and it is in ooxml-schemas

<xsd:attribute name="firstLineChars" type="ST_DecimalNumber" use="optional"/>

So I think it can be achieved, but I don't know what to do
