You can specify that all interfile links in a particular paragraph format should go to the start of the target page instead of to the cross-reference anchor or HyperAnchor PI marker location on the page, by assigning property NoRef to the format. For example:
[HTMLParaStyles]
zNextSection=NoRef
zPrevSection=NoRef
You can assign property NoRef to cross-reference formats, also; see §28.5.2 Specifying HTML options for cross-reference formats.
